Past Updates (2000-2006)

    This is just in case you want to look up something added over the past few years.  Note that the links are not necessarily up to date (especially the external links).

12-26-2006: A quick update, with LK Spanish hadrosaurid Koutalisaurus kohlerorum, Allosaurus europaeus from Portugal, and Turiasaurus riodevensis, giant LJ-EK eusauropod from Spain (with its own group, Turiasauria).

12-13-2006: There are a few housekeeping changes down in Dinosauromorpha (for example, finally cut Arctosaurus), and a new LK Mongolian dromaeosaurid: Tsaagan mangas.

12-2-2006: I changed Ceratopsinae to Chasmosaurinae, and added a dozen or so dubious "prosauropods" in the process of revising Sauropodomorpha.

11-19-2006: In Ken Carpenter's Horns and Beaks, we have four "new" genera.  Three are from reevaluations of older genera: Othnielosaurus consors which essentially takes over for Othnielia rex; Theiophytalia kerri for a skull which had been thought to be Camptosaurus, but actually comes from a much younger formation (keep good and copious field notes, Junior Paleontologists!); and Mantellisaurus atherfieldensis for Iguanodon atherfieldensis, which I'm provisionally accepting in the Giraffatitan/Brachiosaurus vein.  We also have Cedrorestes crichtoni, which not surprisingly comes from a Cedar Mountain Formation member.  Finally, because there had to be a sauropod, we have MJ Chinese Dashanpusaurus dongi, described as a camarasaurid but provisionally listed as an eusauropod. 
11-3-2006: Mid-update update, as the updates were getting crowded, especially with anticipation.  So, we've got new: LTr Brazilian "silesaurid" Sacisaurus agudoensis (along with a large revamp of basal dinosaurs, officially dropping a lot of the tooth genera), EJ South African coelophysoid Dracovenator regenti, EK Chinese titanosauriforms Fusuisaurus zhaoi and Huanghetitan liujiaxiensis, and Chinese LJ basal ceratopsian Xuanhuaceratops niei.  Also, Aliwalia was sunk into resurrected prosauropod Eucnemesaurus, and a link was added to The Paleobiology Database.

9-15-2006: I'm no longer updating this in the manner to which it was accustomed.  We'll see what that means...
    Oh, yeah.  Psittacosaurus lujiatunensis, Maxakalisaurus topai (because there can never be enough titanosaurians of various stripes in 2006), and basal neoceratopsian Yamaceratops dorngobiensis have been added. 

7-19-2006: I've added a navigational table to the bottom of every page but the front page (see this one for an example).  Instead of hunting for links in the pages, you can now find them collected together at the same place of each page.

7-15-2006: Welcome to the new place!  Looks about the same, doesn't it?  One of these days, I should fancy it up, add a hit counter and other such frills.  I take basal ornithopods as site-warming gifts. 
    What's that?  You said you can't get enough sauropods?  All right, meet Zapalasaurus bonapartei, basal diplodocoid from the EK of Argentina.
    You said you still can't get enough sauropods?  Maybe you should get that checked...
    Also, the links page has been heavily renovated, with new links to Aragosaurus.com, Darren Naish: Tetrapod Zoology, Jurassic Harz, The Polyglot Paleontologist, The Tree of Life Web Project, and Wikipedia dinosaur information, along with removing the Internet Archive sites for the time being (I wasn't sure if the original webmasters necessarily wanted their old websites available for viewing). 

6-10-2006: A couple more sauropods for you: Cathartesaura anaerobica, a rebbachisaurid from the LK of Argentina; and dwarf basal macronarian Europasaurus holgeri, from the LJ of Germany.

5-31-2006: I turned in my thesis and moved back to Minnesota, so there's something of a backlog to work through.  There's a little bit for everyone this time around.  For brand new taxa, we have Ligabuesaurus leanzai (Argentinian EK basal titanosaur), Yinlong downsi (Chinese LJ basal ceratopsian), Dracorex hogwartsia (LK flat spiky pachy from South Dakota; see 6-1-2005), Alaskacephale gangloffi (pachy from LK Alaska), Dalianraptor cuhe (EK of China, some kind of birdy maniraptoran), and the by-now standard random sauropod that came out of nowhere, Jiutaisaurus xidiensis, (K of China).  For new species for old taxa, we have a trio of coelurosaurians: Sinornithosaurus haoianus (EK of China), Saurornitholestes robustus (LK of New Mexico), and Gallimimus mongoliensis (LK of Mongolia).  For new genera for old species, we have Agujaceratops mariscalensis. Finally, amid minor changes, I fine-tuned the ages of animals from several Late Cretaceous North American formations (the Judithian stuff), and made note of the Galveosaurus versus Galvesaurus controversy.  Everything here could stand a thorough review.

4-25-2006: Hail, hail, the "Peirópolis titanosaur" finally gets a name: Trigonosaurus pricei.  It joins its bonebed-mate Baurutitan britoi, which was christened at the same time (and I finally tell you about it - I blame it on my thesis).  Both are titanosaurians from the LK of Brazil.  I also updated the two sauropods from April 7th (helpful reader Marcel sent me the pdfs).  
    Just so you know: there's a little disconnect going on in Titanosauria, since some people still use Titanosauridae, and others use Saltasauridae, so I'm sticking with putting those I'm not sure of in Titanosauria incertae sedis.  

4-7-2006: Late March brought us the following news: "MK" Argentinian carcharodontosaurid Mapusaurus roseae (yes, the one known from multiple individuals, been hanging around for years now), LK Antarctic ankylosaur Antarctopelta oliveroi (first published on in 1991), and two Chinese sauropods, ?J eusauropod Yuanmousaurus jiangyiensis and LK ?saltasaurid titanosaurian Sonidosaurus saihangaobiensis.

3-25-2006: Let's see: Erketu ellisoni (late EK of Mongolia, long-necked basal titanosauriform); 2004 updates moved to the archive; and, an aside, the horror of present versus past tense when dealing with the properties of extinct animals was wrestled with for a while before no conclusion was reached.  If it relates to the bony anatomy, I say go with present tense.  If it describes the habits of the living animal, go with past tense.

3-18-2006: Taking a break from my thesis, I bring you Juravenator starki, updating the old "public domain dinosaur" Borsti as apparently a partially-featherless compsognathid from the Late Jurassic of Germany. 

2-26-2006: Oviraptorid Nemegtia is back and better than ever as Nemegtomaia.

2-8-2006: For this update I have the new basal LJ Chinese tyrannosauroid Guanlong wucaii, which you may have seen in the media in all its crested glory.

1-28-2006: I've got: two new names for old faces in Hexinlusaurus multidens for Chinese MJ basal ornithischian "Yandusaurus" multidens, and Dubreuillosaurus valesdunensis for French MJ tetanuran "Poekilopleuron" valesdunensis; two new names in new LK Utah caenagnathid Hagryphus giganteus and LK Argentine titanosaurian Puertasaurus reuili; a lot of additions to the faunal page (mostly African and Asian formations, plus some age work on the LK Mongolian\Chinese localities; one day I swear I will do the South American stuff); and the resolution to the Shuvosaurus saga.  It turns out that Shuvosaurus was a weird early croc relative, bipedal, long-necked, short-armed, and toothless (actually, were its arms longer, and if it had teeth, quite a bit like the Flintstones' Dino).  This is based on the skeleton of a close relative found in New Mexico.  There has been a long and glorious history of confusing early dinosaurs and early crocodilian relatives, from the "teratosaurs" and "predatory prosauropods," to various terrestrial crocs, some bipedal, some herbivorous ("Halticosaurus" orbitoangulatus, Dianchungosaurus, "Stegosaurus" madagascariensis, Hallopus...), to Ornithosuchus, to the revueltosaurs, and now this.  The problem has usually been poorly-preserved LTr or EJ remains, which is when crocodilians and dinosaurs most looked like each other, and was worse in the past, before good LTr and EJ remains were known to show us which was which.  Early croc-related groups did a lot of experimentation, including small gracile bipedal forms (sphenosuchians, Shuvosaurus), quadrupedal armored herbivorous forms (aetosaurs, revueltosaurs), big terrestrial carnivores ("teratosaurs", Ornithosuchus), and a lot of marine forms, before settling into the niches we know them for today. 

1-16-2006: Two new names were added, one being a holdover from 2005, the derived EK Mongolian iguanodontian Penelopognathus weishampeli, the other being the first of 2006, the LK Brazilian saltasaurid Adamantisaurus mezzalirai.  In addition, I'd misspelled Erliansaurus as Erlianosaurus, added a bit on Chirostenotes' hands, duly noted that "Diceratops" and "Microceratops" are preoccupied by insects, and for an encore split Hypsibema and "Neosaurus" for my entry in "Overdue Dubious Giant Hadrosaurid Work 2006." 

12-13-2005: Cleaning up, here and there; also, a new drawing of the alvarezsaurid Shuvuuia. [deleted]

11-27-2005: We have the new horned dinosaur Centrosaurus brinkmani and the new possible ornithischian Krzyzanowskisaurus hunti, along with some updating of dubious hadrosaurids.

11-5-2005: We have a new basal sauropod that's a bit confused over the whole sauropod\"prosauropod" thing (and who isn't, at this point?): Archaeodontosaurus descouensi from the MJ of Madagascar with rather "prosauropod"-like dentition.

10-26-2005: I've had quite a backlog to work through, including: a new basal ornithischian from the EJ of South Africa, Stormbergia dangershoeki, with a reshuffling of basal Ornithischia; a new species of Unenlagia, U. paynemili (actually from 2004, but nobody noticed); Plateosauravus cullingworthi instead of Euskelosaurus anything for valid "euskelosaur" material; new flying dromie-thing of uncertain ultimate placement from LK Argentina, Buitreraptor gonzalezorum, and its related shuffling of Maniraptora; a new proposal on the use of dromaeosaurid claws; new data on alvarezsaurid arms, and a revised placement; more information on the skull of "Psittacosaurus" sibiricus, the patron basal ceratopsian of Thescelosaurus!; a new assessment of "Morosaurus" agilis; new EK Chinese basal neoceratopsian Auroraceratops rugosus; new EK Chinese big-toothed iguanodont Lanzhousaurus magnidens; a fixed link to the new Dinosauricon and a new link to lots of journals; and some more fallout of the Great Revision of Late Triassic North American Dinosaurs, including the following from SVP abstracts: Shuvosaurus inexpectatus is not a dinosaur.  What it really is will blow your mind when it is published. Eucoelophysis is also apparently not a dinosaur, but its identity is not quite as mind-blowing.
    Thus ends the major part of the update (I've still got stuff from the Dinosaur Park volume to add); no doubt there will be some embarrassing typos here and there (such as discovering that I had made up the new taxon Oviraptorosauroidea, and then discovering that I didn't need such a taxon in the first place, and in the second place it should have been Caenagnathoidea because the ghost of Caenagnathus still hovers over the oviraptorosaurians).  Oh, well.  Whenever we think we know something about coelurosaurians, a Buitreraptor bites us in the butt, or jumps up onto a shoulder, hooks in with one of its "killer claws", and starts biting with its little teeth and stabbing in the throat with the other "killer claw".

10-2-2005: We've got a new Chinese oviraptorid, Shixinggia oblita, and some little changes here and there.  In particular, one sharp-eyed reader noticed a typo for Cryptovolans in the Maniraptora cladogram, and there's been some resolution on the Astrodon/Pleurocoelus controversy.

8-17-2005: It's been a good week for basal eusauropods from a variety of places: Chebsaurus algeriensis from the MJ of Algeria (no points for guessing the country), Daanosaurus zhangi from the LJ of China, and Galveosaurus herreroi from the LJ of Spain have all made their entrances.  Also, we get a new basal ornithopod, Changchunsaurus parvus, from the EK of China (first new ornithopod of the year, and about time!).  There's also been a lot of interesting news about who is a basal dinosaur and who isn't, but that'll have to wait until the publications (note plural).

8-1-2005: It turns out that Dianchungosaurus was never a heterodontosaurid, but is actually based on the premaxilla of a valid genus of crocodilian, with the dentary of a juvenile prosauropod referred to it.  Speaking of prosauropods, there's also a brief note on the just-published Massospondylus embryos.

7-12-2005: No sooner have I added one genus than another pops up, this one lurking since 2004: oviraptorid Nemegtia barsboldi from the Nemegt Formation of Mongolia.

7-10-2005: We have our second ornithischian from 2005 (still no ornithopods, though), in Hungarosaurus tormani, a basal nodosaurid from the late Cretaceous of Hungary (no points for guessing the country).  Armored dinosaurs are always welcome here!

7-4-2005: Having just returned from a brief vacation, I bring you all the updates in backlog, plus something new.  In backlog: new data on "Psittacosaurus" sibiricus and the species of "Syntarsus", and a brand-new possible saltasaurid from Argentina, Bonatitan reigi.  Also, I finally was able to retrieve this (the second) image, donated by Randy Knol of Dinosaur Collector Site B, from my departed hard drive.  In breaking news: I ran across Ken Carpenter's The Carnivorous Dinosaurs in a bookshop today, and it looks like I get to be the first to officially welcome Tanycolagreus topwilsoni, new Morrison coelurosaurian, to Internet science, such as it is.  

6-10-2005: I was in a Scientific Illustration class this spring, and for fun our professor, Dr. Dena Smith, put up a web gallery of our work, which you can find on the links page.  This is where my latest Thescelosaurus drawing comes from; since I had a better scan of the pencil version, I thought I'd put it up.  It's kinda large, so if it's causing problems, let me know.  I'm on dialup myself, so I sympathize, and I certainly don't want to cause slow loading for such dubious rewards. [deleted]

6-1-2005: Thescelosaurus! is reaching the end of its term at St. Thomas.  Actually, it was supposed to be deleted on the 31st of May, but I was granted an extension.  So, I'm checking my options (admittedly, the site has several priorities in front of it), and when I find a new home, I'll put the address up here so you can find it.  
    I'd been holding off on updates until I knew what would happen to the site, so I've built up a few.  Of great immediate interest is the revelation I'd been holding onto since SVP, that Revueltosaurus is not a dinosaur but a pseudosuchian.  This has great import for the crop of "Triassic tooth ornithischians" of the last fifteen or so years, which are now cooling their heels (hard to do when you're just a tooth or teeth) elsewhere until more remains are found for them as well.  Sauropods have been well-represented in the last few weeks, with Brachytrachelopan mesai, a new dicraeosaurid from the LJ of Argentina, and Karongasaurus gittelmani, a titanosaurian from the EK of Malawi (the same paper, an electronic publication, has a good review of Malawisaurus as well).  
     On the links side of things, Frederik Spindler has a new website, Dinosauromorpha, now open for your enjoyment and edification.  Also, Dino Russ' Lair has a new address, so I've updated its entry.
     Incidentally, did anyone else catch the new unnamed pachycephalosaurid with no dome but plenty of spikes?  My first thought was a thescelosaur had gone to Halloween with a weird ankylosaur mask.

5-4-2005: I was pleased to see the "Crystal Geyser therizinosaurian" published (see my initial reaction on 11-3-2004 below).  Here it is: Falcarius utahensis.

4-23-2005: After suffering a major hard drive crash (really, is there any other kind?), the preliminary publication of Tyrannotitan chubutensis, an EK carcharodontosaurid, spurred me into action.  As a bonus, Jinfengopteryx elegans, another EK theropod but with a less-certain position, was also added.  Isn't anyone working on anything but theropods anymore?

3-18-2005: Some more theropods for your approval: the Alabama Albertosaurus has been described as Appalachiosaurus montgomeriensis, and a particularly stubborn knot of EK Chinese small theropods has been resolved with Tugulusaurus as a valid basal coelurosaurian, Phaedrolosaurus as an indeterminate theropod, and hindlimb material once referred to it taken out and described as maniraptoran Xinjiangovenator parvus.  Also, Aralosaurus now appears to be a lambeosaurine, and Ozraptor an abelisauroid (both would be the earliest named examples of their respective clades).

3-10-2005: Ekrixinatosaurus novasi, a new Argentine caurnotaurine abelisaurid, has been described (actually, it was described 12-30-2004, but it was described in a journal that took a while to get here).  Also, Crosbysaurus harrisae and Protecovasaurus lucasi, two possible basal ornithischians based on teeth, were added after being formally published, having spent a couple of years as "public domain" dinosaurs: names and information available, but not yet published, and thus not supposed to be discussed.  In addition, there's been some more clarification on Megaraptor.

2-24-2005: "Araucanoraptor" had been described as the dromaeosaurid Neuquenraptor argentinus, from the Late Cretaceous of Argentina.  Now if we could just get someone cracking on "Nurosaurus"...  Also, Eobrontosaurus may not really be Camarasaurus after all.

2-6-2005: A couple of things: Pedopenna daohugouensis, a new feathery beastie (with foot wings) from the Jurassic of China; the reintroduction of (wait for it...) Dravidosaurus blandfordi, black sheep LK Indian stegosaurid; a note on the unfortunate juvenile Psittacosaurus eaten by a mammal; and some new links.

1-15-2005: We have our first newly-named dinosaurs of 2005, oddly enough both from the Callovian (MJ), not a particularly well-sampled time interval: Condorraptor currumili, an Argentinian basal tetanuran, and Ferganocephale adenticulatum, a Kyrgyzstani possible pachycephalosaurian.

1-8-2005: Just a little tune-up in the ornithopod chunk of the tree...

1-3-2005: I've finally gotten around to adding an old drawing of Acrocanthosaurus; unfortunately, the scan is not as nice as I'd like. [deleted]

1-2-2005: Another day, another year, another massive reorganization of the base of Sauropoda, including a vast increase in Sauropoda incertae sedis.  The highlights include: blowing up Euhelopodidae and spreading its remains among Sauropoda and the brand-new Eusauropoda; and busting Camarasauridae down to Macronaria.  Also, it was about time, so I gave Nodosauridae its own page, and put the updates from 2002\2003 on the archive page.  

12-28-2004: I finally got around to fixing the armor on Sauropelta, and decided that it would be a good idea to split off the old-style drawings, now in their own archive. [deleted]  Also, Rinchenia is now official (or, it had been for a while, but nobody was quite sure).

12-27-2004: Yeah, I gave up the Paulian secondarily-flightless maniraptorans.  Anyway, I'm adding new information from the second edition of The Dinosauria, and I hope to be done sometime before the third edition comes out.  I've added Limaysaurus tessonei, rebbachisaurid rescued from nomen nudum-dom, and synonymized Eobrontosaurus with Camarasaurus.  The main changes are to be found in a heavy reorganization of most of Theropoda (I haven't gotten to some of the maniraptoran groups yet, but I wanted to put up the revisions because of how badly out-of-date they'd been).  So, if there are weird grammatical and formatting mistakes, that's why.

12-2-2004: I've added several new links, including three museums and two sites, on toy dinosaurs, just for fun.  Also, we've got a new Brazilian prosauropod on our hands: Unaysaurus tolentinoi.  Finally, a new paper on European coelophysoids has spurred me to switch a few theropods into Coelophysoidea (including Zupaysaurus) and adjust some age assignments.

11-3-2004: A few minor changes have been made, including an SVP-mediated change of heart on a couple of shady therizinosaurian-mimics (busted Eshanosaurus down to Saurischia incertae sedis, and sent Protognathosaurus to Sauropoda).  My copy of The Dinosauria II has arrived, but because I wasn't expecting it until December, I had it sent to the family address, so I don't get to see it for a while.  At any rate, having it here would have been a major distraction, so maybe it's better if it's not here.  I'll just keep telling myself that...  

10-13-2004: Sleepy subadult troodontid Mei long makes its appearance.  The paper describing this new Yixian theropod, along with other new information, has allowed me to clarify the ages of some of its dinosaurs.

10-6-2004: Thescelosaurus! is five years old today!  I didn't think it would last that long, but here we are!  Hopefully, it lasts many more years, at some location or another (I know one day it will have to leave the friendly confines of St. Thomas, I just don't know when, or to where it will go).  I've added a brief introduction that covers the Dinosaur Dictionary tradition and how it formed this site, and I've decided that major changes to content, except for new taxa additions, will probably wait until December at the earliest, when I should be getting the second edition of The Dinosauria.  I think I'll have a better idea of the site's physical future by then, too.
   Speaking of new taxa, we've got Borealosaurus wimani, a new eLK Chinese titanosaurian with opisthocoelous mid-distal caudals.  Having only seen the abstract, I'm not sure how it was assigned to the titanosaurians, but given the morphology, I've tentatively placed it with the opisthocoelicaudiines. I've also got for you a new feathered critter, this time a basal tyrannosauroid: Dilong paradoxus, from the Yixian (where else?) of China.

9-23-2004: Nothing dinosaur-related, but I just wanted to let you know that I have redressed a wrong and added to my acknowledgments on the "biography" [deleted] page.

9-19-2004: Prenoceratops pieganensis, a new leptoceratopsid, has been added, leading to a reorganization of the basal neoceratopsians; among other things, Breviceratops has been sunk into Bagaceratops (actually, it happened a while ago; I just hadn't sat down and made the change).

9-11-2004: Bonitasaura salgadoi, a new titanosaurian from the LK of Argentina, shows that rebbachisaurids didn't have the market covered when it came to squared-off jaw tips, and throws in something of its own: sharp ridges on the lateral margins of the jaws, suggesting a beak-like cutting surface behind the teeth.

8-30-2004: Just doing some housekeeping, mostly in Ceratosauria, Abelisauridae, Sauropodomorpha, and Sauropoda.  Highlights: Ammosaurus is officially sunk into Anchisaurus, Unquillosaurus is apparently a maniraptoran, and it now appears that Indosaurus didn't have horns and may have been the same as Indosuchus (which if true would tend to cut down on the "Indo" confusion).

8-13-2004: A couple of little things have been changed.  Most important are: the new Brazilian compsognathid Mirischia asymmetrica, previously known to its adoring fans as SMNK 2349 PAL; and a brief mention of the new tyrannosaurine growth study.

7-9-2004: The link for the Archives of the DINOSAUR Mailing List has been updated.

6-27-2004: Kerberosaurus manakini, a new hadrosaurine (described as closest to the saurolophinids) from the Amur region, has been added. 

5-21-2004: I've got a new basal dromaeosaurid\deinonychosaurian theropod for you, Graciliraptor lujiatunensis from the Yixian of China, and a couple of new images: Coelophysis bauri and Thescelosaurus neglectus. [deleted] Apparently I'm not on the list to be cleaned off of the server yet, so I get another semester.  Do you think I should just buy a "The Site is Coming to an End" sign for all these defused alarms?

5-9-2004: Here's a Gargoyleosaurus illustration I did over a year ago that I've been holding onto [deleted]; also, some bad news: Palaeos is apparently going out of business.  It's too bad, because a lot of the good dinosaur\paleo sites of the past are either not updating or updating sporadically compared to what they once did.

5-6-2004: What?  Another new dinosaur?  Yes, it's Suuwassea emilieae, a new diplodocoid from the Morrison Formation of Montana, and it has occasioned a reorganization of the Diplodocoidea page (welcome the rebbachisaurids).

5-3-2004: Update on the fly: hot off the press is a new basal iguanodontian from the LK of Patagonia, dubbed Talenkauen santacrucensis.  You may have run across it earlier in association with National Geographic.

5-1-2004: No sooner had I posted the last update, than three new names pop up.  First, Tazoudasaurus naimi (which had been announced earlier), a basal sauropod from the EJ of Morocco, has been published.  Second, two long-rumored ceratosaurians have been described: Spinostropheus gautieri, a new name for what has turned out to be a basal ceratosaurian from the EK of Niger; and Rugops primus, a new basal abelisaurid from the early LK of Niger.  Also, someone should have told me that I was being a great lummox and that it's the articular, not the angular, that becomes the malleus in mammals.  Well, now it's fixed for all time, so the opportunity for you to be a hero is gone.  Mmph. 

4-29-2004: As promised, a few new links:
The Theropod Database, new home of Mickey Mortimer's theropod musings;
The Dinosaur FAQ, for those important questions; and
MESOZOIC DINOSAURS, including its database of online dinosaur scientific papers, for when you've graduated from The Illustrated Encyclopedia of Dinosaurs and want to sink your teeth into the technical literature.

4-25-2004: To let you know I'm still here and thinking of you: Bissektipelta archibaldi (a new name for "Amtosaurus" archibaldi), new troodontid Sinusonasus magnodens, and new dromaeosaurid Atrociraptor marshalli have been added.  I've got some links I'd like to add, and I haven't had time to clean up this place as much as I'd like, so keep an eye out for those changes.  The site probably has a month or so left at this location (for real this time, because I checked), but I have a couple of options for its future.

3-11-2004: Huaxiagnathus orientalis, a new large compsognathid, has been added.

2-14-2004: I've been adding stuff from the third supplement for a while now.  Some more prosaic changes include removing the a, b, c, etc from citations, because I realized that they didn't mean anything outside of context, and the time chart has been brought up to date.  Also, I added the new Argentine saltasaurid Rinconsaurus caudamirus.

1-17-2004: Actually, there's not much going on, but I reorganized some of Sauropoda (the main change is that Euhelopodidae is now separated from the diplodocoids).  Gobititan shenzhouensis is now an official published titanosaurian, and the dicraeosaurid Amazonsaurus marahensis has been added.  I've got some new resources (the third supplement to Glut's encyclopedia, most importantly), but I haven't yet used them for revisions.  I'd also like to clean up Euhelopodidae some.

12-12-2003: I bit the bullet and heavily revamped Macronaria, Titanosauria (the old Titanosauridae), and Saltasauridae (a brand new page for the old "saltasaurines" and the opisthocoelicaudiines).  This was prompted by the redescription of "Titanosaurus" colberti, now Isisaurus.

12-7-2003: A new toothed ornithomimosauroid from China, Shenzhousaurus orientalis, has been added, along with other minor changes here and there.

11-3-2003: I've just been cleaning house, moving things about, and so on.  The biggest news is cutting the confuciousornithids, because they were kind of out of place on this website.

10-10-2003: I had to address a link: Pachycephalosauria is no longer functioning, but along with its fellow defunct marginocephalian site Ceratopsia, if you'd like to see what it had, you can use Internet Archive.

9-28-2003: I've got a little bit of everything for those with eclectic tastes.  For those who like their iguanodontians basal and obscure, check out Zalmoxes and the resurrected Mochlodon; for those who like their tyrannosauroids tiny, there is Aviatyrannis jurassica from Portugal; for those who like their sauropods small and basal, I have received reports of Morocco's "Tazoudasaurus naimi"; finally, for those who prefer their horned dinosaurs without much horn, we have three new neoceratopsians for you (nyuck nyuck nyuck!): Lamaceratops tereschenkoi, Platyceratops tatarinovi, and Magnirostris dodsoni.

9-3-2003: Well, I've finally gotten an update through!  I've been adding things behind the scenes for a few weeks now (mostly simple additions of new names, as I've been busy with the start of grad school).  Here's a quick rundown. Antetonitrus ingenipes is a new basal sauropod that has spurred reorganization of Sauropodomorpha (betcha didn't expect to see Anchisaurus a sauropod, eh?); Thecodontosaurus caducus is a new species of an old favorite; Megaraptor may actually be a carnosaurian; Serendipoceratops arthurcclarkei gives a name to the Australian neoceratopsian ulna from a few years back; Yixianosaurus longimanus is a new small maniraptor, possibly with arboreal inclinations; Rajasaurus narmadensis is a new carnotaurine from India; Mendozasaurus neguyelap is a new titanosaurian; Zupaysaurus rougieri is a new basal ?tetanuran with head crests; and Shuangmiaosaurus gilmorei is a new derived iguanodontian.

7-14-2003: In the words of George Harrison, "it's been a long long time" ("Apple Scruffs," and now that I think of it, almost "Long Long Long" as well).  I've got a few new names up, and a new link, to Steven Mahon's Classifosauria.  You will now find the basal neosauropod Ferganasaurus verzilini, the "psittacosaur"-grade Hongshanosaurus houi, the neoceratopsian Bainoceratops efremovi, and the basal ornithomimid Sinornithomimus dongi.  There's a couple I have yet to add for various reasons (one, Antetonitrus, is a new basal sauropod, which is going to cause me to revamp a great deal of basal Sauropodomorpha; if you've been following the DML, you'll know why).

6-9-2003: Update: It turns out I get two semesters after I graduate before this is deleted.  However, I won't be updating much this summer, and I'm still planning on moving this site, because I can't really work on it outside of the network.

5-22-2003: Well (I seem to lead off these updates with "well" a lot lately), I'm anticipating that this will be the last update made to the website at this address.  Soon this incarnation will disappear from the Internet, hopefully to be replaced before too long.  I figure I'll do some tidying up while it's offline, but don't expect that the format will completely change.  So long for now!

5-18-2003: Well, first of all, Thescelosaurus! will be going off-line shortly, due to me graduating from St. Thomas and this site expiring from the St. Thomas server.  I promise that it will not go extinct like its namesake, and am considering a couple of options for future location.  At any rate, it will disappear at the end of the month and probably not reappear until toward the end of summer.  All those with websites with links here take note!  Location will be changing!
    So, after all that, some dinosaurian goodness.  Dromaeosauroides bornholmensis, Denmark's first named classic dinosaur, and Lusotitan atalaiensis, a new name for an old brachiosaurid, have been added.

5-7-2003: A bit of work on the prosauropods: Efraasia has been reinstated, and Sellosaurus sunk into Plateosaurus.

4-23-2003: As promised, a bit of revision of Cetiosaurus and its numerous species...

4-21-2003: Well, I've been sitting on these for a while now, but it appears that I am the only person who has yet received their copy of the latest Journal of Vertebrate Paleontology.  Added to the site are Struthiosaurus languedocensis, a new French species of the famous miniature nodosaurid, Fukuisaurus tetoriensis, a derived iguanodontian from Japan (which older patrons may recall from years ago as a nomen nudum), and two pachycephalosaurids, Colepiocephale lambei and Hanssuesia sternbergi (necessitating yet another overhaul of the North American pachies).  There's also an article on the taxonomy anatomy of Cetiosaurus, which I will get to later.

4-5-2003: I performed a major taxonomic overhaul on the North American pachycephalosaurids.

3-10-2003: I fixed the links to Pachycephalosauria and the Tree of Life pages (tyrannosauroids and ankylosauromorphs).

3-5-2003: Continuing housecleaning...

3-2-2003: Just doing a bit of long-delayed cleaning...

2-2-2003: This place could stand a major overhaul.  Anyway, several new taxa have appeared: Pycnomenosaurus nevesi, a Brazilian abelisaurian; "Olorotitan archarensis", a Russian hadrosaurid; Heyuannia huangi, a Chinese oviraptorid; two species of an American pachycephalosaurid, Sphaerotholus; and, finally, the famous "four-winged" dinosaur Microraptor gui.

1-6-2003: It's not really an update; I'm just checking in to let you all know that I haven't abandoned this place.  I've just been busy, and there hasn't been a lot of major stuff to come down the pipeline as of late.

11-12-2002: A number of new taxa were added, most of them unofficial at this point.  We now have ankylosaurian Crichtonsaurus bohlini, titanosaurian "Gobititan shenzhouensis", possible basal hadrosauroid "Equijubus normani", and basal dinosaur "Silesaurus opolensis".

11-11-2002: I'm halfway through a minor taxonomic update.  So far, Epidendrosaurus and Shenzhouraptor have been made official.

10-30-2002: Well, it's been a while, and I'm just checking in to let you all that I'm still around.  I've spent a lot of time in the last month working on a poster for GSA, and I just got back from the Denver conference, so I *should* have more time to look at this old friend.  I picked up some new references at the conference, including a paper with a wonderful summation of the dinosaurian fauna of the Morrison, met a few well-known paleontologists in person, like Kenneth Carpenter, Karen Chin, and James Farlow, and in general had a terrific time!

10-1-2002: A few additions: first, iguanodontian Anabisetia saldiviai is no longer a nomen nudum; second, tetanuran ?Poekilopleuron valesdunesis and basal oviraptorosaurian-therizinosaurian Incisivosaurus gauthieri have been added.  In other news, we are rapidly closing on the fourth [future Justin: Third, you moron!  Third!] birthday of the site; my file manager informs me that the index page was created on October 6, 1999.  Any way you slice it, this site has spanned two centuries! (in a very minor fashion, of course)

9-10-2002: I added a page detailing my information sources, and also move all the updates from 2001 and earlier to a separate archival page.

9-9-2002: Back to the theropod side of things, there's been some taxonomy to catch up with.  The Yixian and allied Chinese formations (the stratigraphy has gotten a little more complicated lately, but we'll see these things cleared up) are putting out even more small theropods (this just gives one an idea of how diverse small theropods really were; unfortunately, it takes special depositional environments to catch 'em); so far, I've added Scansoriopteryx heilmanni and "Epidendrosaurus ningchengensis", both small possible tree-climbers, the former with feather impressions; Jinzhouornis yixianensis and J. zhangjiyingia, confuciousornithid species; Omnivopteryx sinousaorum, an ?oviraptorosaurian and possible flyer; Cryptovolans pauli, a dromaeosaurid and possible flyer; and, for a change of pace, there is the LK tyrannosaurid "Tyrannosaurus" zhuchengensis.  Archaeovolans repatriatus, based on the front end of "Archaeoraptor", may end up here as well.  As usual with new species, their entries aren't the most detailed.  However, just the descriptions make me salivate.  Flying dromaeosaurids?  Tree-climbing theropods?  This is one of the reasons why I love dinosaur paleontology: you never know what amazing things will turn up next
    In addition, I've added two new links: Palaeos, which includes the material from Toby White's Vertebrate Notes; and The Plesiosaur Site, because I like plesiosaurs too.

9-3-2002: A brand-new page has gone up: Polacanthidae.  This is part of a restructuring of the pages on Ankylosauria (I should probably add one for Nodosauridae, but that would be quite a task, given all of the cross-referencing on this site).  I picked up a few books over August, one of them being The Armored Dinosaurs (Carpenter [ed], 2001), which has inspired me to such work.

8-1-2002: Two new flying theropods from the Yixian, Jeholornis prima and "Shenzhouraptor sinensis", have been added, along with a new therizinosaurian, Erliansaurus bellamanus, from the ?Santonian of China.  Aucasaurus garridoi has been upgraded from a nomen nudum, and another species of Psittacosaurus (P. liangi) has appeared.  Don't worry; I will get around to Mongolia! [04-2010: sorry, never did]

7-24-2002: Well, I would have filled you in, but I ended up working a great deal longer per day than I anticipated, so I've yet to organize my thoughts into a coherent posting.  On the other hand, I've added a few tidbits, including an overlooked species of Psittacosaurus (P. sibiricus), and the recently-published news that a specimen of that genus, from the Yixian, preserves bristles on the tail.

7-11-2002: Sorry, not dinosaur news; I'm just posting quickly that I'm back.  I spent the month of June in Mongolia (not for dinosaurs, but I certainly saw some beauties in the museums!), and I'll fill you in more on my trip in the next few days.

5-22-2002: I'm sorry for the lack of updates, but news has been light and times have been busy at my end.  I'm just checking in before I sign off for the summer (and for a bit of an adventure; remind me to post on it when I get back).

4-30-2002: Chasmosaurus irvinensis has finally made its debut in Ceratopsinae (I'd actually forgotten about it for a while).

4-27-2002: A few changes: first, I've linked with Ischigualasto.org (hence the new banner on the front page); second, "Amtosaurus" archibaldi, a new ankylosaurid from Uzbekistan, has been added; finally, the color of the site has been lightened and the front page spiffed up a bit.  Interestingly, the green bars on the front page seem to only show up when Internet Explorer is used.

4-21-2002: "Stegosauroidea" is now Stegosauria.

3-22-2002: Liaoceratops yanzigouensis, a basal neoceratopsian from the Yixian, was added.

3-11-2002: With the addition of a great deal of material to Stegosauroidea, including to my already lengthy comments on Stegosaurus itself, the latest revision of the site's information is finished.

3-9-2002: I've made some big changes at Avetheropoda.  The page itself has been dismantled, its contents spread over Tetanurae and the renamed pages Coelurosauria (Neocoelurosauria has bit the dust) and Carnosauria.  Within Coelurosauria, the basal members of Tyrannosauroidea and Ornithomimosauria joined their more derived relations in their own renamed pages.

3-4-2002: Among other changes as I wind down my revisions, there has been some reshuffling in Avetheropoda, Neocoelurosauria, and Allosauroidea (which has also had its link renamed).

2-15-2002: Sinovenator changiae, a new basal troodontid from the lower Yixian, has been added, an addition which also changed the arrangement of Maniraptora.

2-10-2002: Syntarsus is now "Syntarsus" because of issues with the renaming.

2-7-2002: I've added some brief notes on the major bones of the dinosaurian skeleton, which I plan to expand upon and provide illustrations for later.

2-4-2002: Agnosphitys cromhallensis, a possible basal dinosaur from the late Triassic of England, has been added.

2-2-2002: Syntarsus has proved to be preoccupied by a beetle (Fairmaire, 1869), so the name Megapnosaurus has been substituted.

1-31-2002: Two new taxa were added: basal bird Sapeornis chaoyangensis and ceratopsian Protoceratops hellenikorhinus.

1-30-2002: Bradycneme has been reinstated, among other changes.

1-29-2002: Among other recent changes, "Opisthocoelicaudiidae" has been moved within Macronaria.

1-8-2002: I'm working on adding a lot of notes, having received the second supplement of Glut's encyclopedia and the Isle of Wight dinosaur volume last fall without having had much time to read them until recently, and I'm considering adding a few additional pages, dealing with things like how dinosaurs fit among other reptiles, thermoregulation, extinction, and growth; topics that don't really fit on the other pages (I'm also starting to think I should archive the old updates, so this page isn't so long!).  So, nothing really exciting has been added.

12-19-2001: I've updated the Paleo Ring information (unfortunately it no longer has the cool Archaeopteryx pictures).  I'll also be going on hiatus until the end of January; updating will be infrequent until then, but I plan on getting a large update together.

12-9-2001: Pukyongosaurus millenniumi, an EK South Korean euhelopodid, has been added.

12-2-2001: Gobisaurus domoculus, an EK Chinese shamosaurine (another ankylosaurian!), has been added. 

11-20-2001: Yet another new ankylosaurian has come down the pipe (not that I'd ever complain about a new ankylosaurian, or any other dinosaur for that matter, but it's been quite a fertile year for ankylosaurians as of late), the unofficially-named "Hanwulosaurus", a large Chinese taxon.

11-17-2001: Two new dinosaurs have been published, both from the Cretaceous of China: Neimongosaurus yangi, a long-necked therizinosaurian; and Jiangshanosaurus lixianensis, a titanosaurid.  I've also changed the links a bit; the old Lourinhanosaurus site has been set up at Dinodata.

11-4-2001: Well, there's a lot of minor pruning I've been meaning to get to, but I haven't had the time to do it.  I haven't been able to keep up well with changes in the Dinosauria lately, even though it's been seemingly low volume.
    Anyways, among other small changes, "Laelaps" gallicus has been synonymized with Streptospondylus.

10-28-2001: The Wealden revision is coming, along with a reassessment of Streptospondylus.  The new species of Chasmosaurus is C. irvinensis, a Canadian species known mainly from distinctive skulls with a large nasal horn, no brow horns, and a unique configuration of epoccipitals.  As soon as I get the name of the describer (or describers), I'll post it in Ceratopsinae.  Meanwhile, I added three new images: Apatosaurus sp., Parksosaurus warrenae, and Syntarsus [now Megapnosaurus] rhodesiensis. [deleted]

10-23-2001: A few small changes: I've pruned the species of Ceratosaurus and synonymized Seismosaurus with Diplodocus.  Expect a revision (again!) of the Wealden sauropods, and a new species of Chasmosaurus.

9-30-2001: A mixed bag: first, we have three new names: Aletopelta coombsi, a new Californian ankylosaurid; Cedarpelta bilbeyhallorum, another ankylosaurid, the final name of "Bilbeyhallorum"; and Wellnhoferia grandis, a new generic name proposed for a specimen of Archaeopteryx (and which I'm considering to be a generic synonym for the time being).  Next, we have Hesperosaurus mjosi, the new basal stegosaurian from the Morrison, published.  Finally, in keeping with the armored dinosaur theme, I've added a new personal drawing, of Sauropelta. [deleted] 

9-6-2001: I've cleaned up a few things, made Nothronychus official, and added Eshanosaurus deguchiianus, another new therizinosaurian, from the early Jurassic of China.

8-20-2001: I've finally added the last of the new names.  Today we have "Nothronychus mckinleyi", a new New Mexican therizinosaurian; the reinstatement of the erstwhile earliest ornithomimiosaurian Shuvosaurus inexpectatus; the new juvenile ankylosaurian Liaoningosaurus paradoxus; from Madagascar, the new titanosaurid Rapetosaurus krausei (including an extremely rare titanosaurid skull); the new basal Chinese sauropod "Yibinosaurus zhoui"; and "Hesperisaurus", a basal ?stegosaurid from the Morrison.  Now that all of the new taxa have been added, I'll work on updating some prior material. 

8-16-2001: I'm continuing to add names and information.  Today we have Venenosaurus dicrocei, a basal titanosaurian from the Cedar Mountain Formation; Planicoxa venenica, a new iguanodontian also from the Cedar Mt. Fm.; newly-described Chinese ?ankylosaurian Bienosaurus lufengensis; Quilmesaurus curriei, a new small to medium sized theropod from Argentina; and two new Mongolian oviraptorids, Citipati osmolskae and Khaan mckennai.  I have another half-dozen names to add, but computer problems are limiting my time today.

8-14-2001: I'm beginning my fall update now.  There's been quite a lot of new names published in the last three months; here's a few of them: "Proornis coreae", a possible North Korean confucuisornithid; "Aucasaurus garridoi", a new Argentine carnotaurine; Paralititan stromeri, a new giant Egyptian titanosaurid; Losillasaurus giganteus, a new Spanish diplodocoid; Jinzhousaurus yangi, a new Chinese iguanodontian; and Ruehleia bedheimensis, a new German plateosaurid. 

7-17-2001: I'm just writing to let you know I'm still around (and I'm collecting quite a lot of new names to put up when I have more time).  To show you my good intentions, I've removed Velocipes' entry (it managed to escape the Purge of 5-2-2001) and removed Patricosaurus, which is probably non-dinosaurian.

5-17-2001: Nothing's really new today; I'm just writing to let everyone know I won't be around to update much for the next few months (reduced access due to going back home for the summer).

5-9-2001: Eotyrannus lengi, a new Early Cretaceous Wealden tyrannosauroid, has been added.

5-3-2001: Continuing with yesterday's Great Theropod Clean-Up, I made a few more changes, most importantly reinstating Saurornitholestes, moving Sinornithosaurus down to Deinonychosauria, and removing Ricardoestesia and "Beelemodon" from Troodontidae.

5-2-2001: I've made several changes, mostly in the theropods.  First, Velocipes, Rileyasuchus, "Massospondylus" rawesi and Liliensternus orbitoangulatus have been shown to be non-dinosaurian.  Second, "Labrosaurus" stechowi has been referred to Ceratosaurus, and "Labrosaurus" ferox and "Wyomingraptor" have been referred to Allosaurus.  Third, Megalosaurus cambrensis is now "Newtonsaurus".  Fourth, Siamosaurus, Aristosuchus, and (very provisionally) Lewisuchus have been reinstated.  Finally, the new Lourinha camptosaurid Draconyx loureiroi has been added.  I'd like to thank here Mickey Mortimer, a regular contributor to the Dinosaur Mailing List who has devoted a great deal of time and effort on the theropods, for his information and suggestions, which have greatly helped me fix problems and inaccuracies in that group.

4-22-2001: Spondylosoma has been shown to be non-dinosaurian.

4-11-2001: I've been doing some alterations with the Morrison sauropods.  Nothing major has happened, but I have reinstated Camarasaurus grandis, Diplodocus hayi, and "D." lacustris.  Also, the Paleo Ring is now in operation!

3-26-2001: Well, this isn't a real update.  Nothing much has been happening, and I've been extremely busy.  I haven't forgotten about the site, though.

2-12-2001: I added a lot of material to the Centrosaurine page, mostly dealing with recent discoveries about their growth and implications for certain genera.

1-29-2001: I just got back from a J-term trip to the Southwest, and I found a few interesting things when I got back: first, additional information on the small theropod "Aniksosaurus"; next, the first dinosaur of the new millennium, the spinosaur-jawed noasaurid Masiakasaurus knopfleri of Madagascar, named in part for musician Mark Knopfler of Dire Straits, was published; and the tyrannosaurids are in the midst of an overhaul, with the aublysodontines going the way of Fabrosauridae (so long, Stygivenator). 

1-4-2001: A few changes: I added the new ?ornithopod Jeholosaurus, reinstated the nodosaurid Stegopelta, and added links to the two dinosaur pages on The Tree of Life, Ankylosauria and Tyrannosauroidea.

12-14-2000:  The basal allosauroid Fukuiraptor kitadaniensis, once known as the large dromaeosaurid "Kitadanisaurus", has been added.

12-6-2000:  First of all, I've updated Ilokelesia now that it's been officially published.  Second, and more importantly, a new feathered theropod from the Yixian has been announced.  Microraptor zhaoianus is a tiny dromaeosaurid-like maniraptoran. 

11-29-2000:  Things have been pretty slow lately; I've added two new taxa, "Bienosaurus crichtonii", a basal thyreophoran, and Rocasaurus muniozi, a saltasaurine titanosaurid, and updated a third, Graciliceratops mongoliensis, a basal ceratopsian.

11-13-2000:  I've got some minor changes to report; most importantly, I rearranged Tyrannosauridae somewhat (bringing back Tarbosaurus, among other things), and returning Stegosauria to Thyreophora. 

11-5-2000:  Not much has changed; I'm assimilating some of the new findings from the 2000 SVP (Society of Vertebrate Paleontology) meeting into the site, including an expanded Noasauridae of Abelisauria and a clade Leptoceratopsidae in Neoceratopsia. 

10-15-2000:  I've added a (rather large) diagram of a dinosaurian skull and some additional supporting text to the glossary. 

10-8-2000:  I've revised some of the classifications of dinosauromorphs and early dinosaurs, particularly the herrerasaurids. 

10-1-2000:  Nothing earth-shattering has happened; I've added a couple more of my illustrations [deleted], and reworked the front page somewhat.

9-26-2000:  I finally added some more images!  There are a few photos I took at the old Science Museum [moved to main image page], and a couple of my own pieces [deleted], so go take a look!  Plus, I've started work on a glossary of important directional and anatomical terms.  In other news: I've gotten sick of fiddling with the hit counter, so I dropped it for the time being; Camposaurus arizonensis has been shown to be most likely a specimen of Coelophysis; and Anasazisaurus and Naashoibitosaurus have been shown to belong in Kritosaurus.

9-24-2000:  A couple of taxonomic changes have been made, both somewhat embarrassing: Agrosaurus macgillivrayi is not from the late Triassic of Australia, but is a mislabeled specimen of Thecodontosaurus from England (and I missed noticing it for over a year!); and "Dinosaurus" is not actually a poorly-known theropod from India, but a non-dinosaur, a therapsid (a so-called "mammal-like reptile").

9-17-2000:  I've finished adding my notes.  Among the many rather small changes, the status of "Struthiosaurus" transylvanicus versus Struthiosaurus has altered. 

9-12-2000:  Just a couple of quick changes have been made.  Most importantly, the DinoLand Web Ring has changed its affiliation, so I reworked my banner.  In addition, the new informally-described ornithomimid "Ginnareemimus" has been added.

9-11-2000: A large number of minor changes have been made to many pages, as I continue to work on transcribing my offline notes.  Many newer taxa have been updated.

9-6-2000:  A couple more names have been added.  First is Isanosaurus attavipachi, the first known Late Triassic sauropod.  Second is Glyptodontopelta mimus, a "stegopeltine" ankylosaurid.  Also added was a new species to an old taxon: Edmontonia australis.  Also, a couple of species of Stegoceras have been reassigned to its relative Prenocephale.  

9-5-2000:  A few names have been added: the late Maastrichtian lambeosaurine Charonosaurus jiayinensis and the iguanodontian Nanyangosaurus zhugeii.  Also, Huabeisaurus allocotus has been updated.  A few other small changes have been made, and since I'm back in school, I plan on having regular updates again.  The hit counter looks different, but is still not functioning, so I might just dump the thing.  If you came to this page through the original location, http://personal2.stthomas.edu/jstweet/index.htm, you can also reach this site at http://personal2.stthomas.edu/JSTWEET/, which has the same material.

8-9-2000: A lot of changes have been made, and I'm nearing completion of my update.  Most importantly, a link to The Ceratopsia Home Pages has been added, Sigilmassasaurus has been returned along with some housekeeping in Spinosauria, the new sauropod Chuanjiesaurus anaensis has been added (this is becoming a banner year for new sauropods), the Jurassic time scale has been updated, and the position of Protognathosaurus has been revised, with a new personal hypothesis.  A number of other small changes have also been made.  Note-there appears to have been a glitch with my hit counter, and it has reset inadvertently.

7-25-2000: I continue to peck away at my notes.  The largest change I made today involves which species are assigned to Allosaurus and A. fragilis.

7-11-2000:  Massive changes to Sauropoda have been made.   Most important: Camarasauridae has been moved to Macronaria, and Diplodocimorpha has been dissolved.  Also, three new taxa have been added: Nqwebasaurus thwazi, a basal coelurosaurian; Pyroraptor olympius, a dromaeosaurid; and Caudipteryx dongi, a new species of the ?basal oviraptorosaur Caudipteryx.  I have a number of additional notes to transcribe, but my time is short right now.  Stay tuned for a major update.

5-31-2000: I was able to get in for a short time and add some new species to Ceratosaurus.

5-18-2000: Nomingia gobiensis, an unusual oviraptorid, and "Chiayusaurus" asianensis were added.  This is going to be my last update for a while.  I hope to have some more links ready when I get back, and maybe some more images.

5-15-2000: "Iguanodon" exogyrarum was added, along with additional comments on the unusual sauropod Opisthocoelicaudia.  I've also decided what form the anatomical guide will take: I plan to have one full skeletal illustration for overall reference, and then smaller subsections, like the skull, for giving greater detail.  I also plan on including information about the various directional words.  I expect to have all this ready to add when I come back from summer break.  Don't be alarmed if you don't see regular updates during the summer; I won't have the same sort of regular access to the server and other resources for a time. 

5-10-2000: Not much to say; finals are coming up.  Janenschia was revealed to be a possible camarasaurid.

5-2-2000: A lot of minor changes were made.  Therizinosauroidea is now Therizinosauria.

4-27-2000: I've revised some of my pages to make them fit better with established definitions.  Thus, Brontosauromorpha is now Diplodocimorpha, Titanosauria is now Macronaria, and Neoceratosauria is now Ceratosauria.  Also, Camarasauridae and Brachiosauridae have been given their own pages.

4-25-2000: Two new sauropods, "Bashunosaurus kaijangensis" and "Huabeisaurus allocata", have been added.

4-20-2000: Page U-V-W-X-Y-Z is now up.  Finally, the alphabetical index is complete!

4-19-2000: All the alphabetical pages have been reconfigured with a larger font, and the T page has been added.

4-18-2000: The S page is now up.  I've been very busy lately, so I haven't been able to work as much on this site as I'd like.  There are some things I'd like to clear up, especially in my classifications, but I haven't yet had the time to get around to it.  Among those is the size of the font I use for the alphabetic index pages, which I've noticed shows up really small on some displays.  Thus, I'm changing it to the same size I use for all my other pages.   I have the A and N pages set up like this now, so you can see if you like it.

4-13-2000: Tendaguria tanzaniensis, a new sauropod taxon, has been added, and the Q-R page is now up.

4-11-2000: The P page is now up.

4-6-2000:  The O page is now up, and I've taken care of some odd glitches that made the L and N pages appear entirely in italics.

4-4-2000: Thescelosaurus! now has images (well, only one right now, but that will grow)!  There's now a photo of a Thescelosaurus mount that Steve Brusatte of The Official Dino Land Website has generously allowed me to add.  Also, the N page is up.

3-30-2000: The M page is now up.

3-28-2000: Some minor changes have been made here and there; most importantly, I did some work on Pleurocoelus and Pelorosaurus, and the result is three new entries: "Pleurocoelus" altus, Dinodocus mackesoni, and Ornithopsis hulkei.  The L page is also up.  In reference to the improvements I spoke of on the 16th, I've also been working with images, and as soon as I can get them working the way I want them to, I'll have some up, including (I hope) a good skeletal diagram.

3-17-2000: Last-minute additions: Bambiraptor feinbergi, a new maniraptoran; Yandangornis longicaudus, a new advanced theropod that may be a bird; and some repositioning of Alvarezsauridae.

3-16-2000: The H and I-J-K pages are now up, and I've added "Byronosaurus jaffei", a new, undescribed troodontid.  I'll be going on a week's break shortly, and I might have some improvements to add when I get back, so stay tuned.

3-14-2000: The G page is up, and I've a few minor changes to a couple of pages (I've now recognized Giraffatitan as its own genus).

3-9-2000: The E-F page is up, and the abelisaurids and therizinosauroids have been given their own pages.  Plus, I got the images for the Paleo Ring to work!

3-8-2000: I decided to give up the "Eutheropoda" stuff, and made Neoceratosauria the whole business of the old "eutheropod" page.

3-7-2000: The C and D pages are now up.

2-29-2000: I've put the B page up, reorganized some of my Titanosauridae and Titanosauria information, and added two links, to The Lourinhanosaurus Web Page and to Pachycephalosauria.

2-24-2000: I've put up the starting page for the alphabetical index of taxa, and linked it up to the A page, so you can get an idea of how the thing will work when completed. 

2-23-2000: There have been several important additions.  First, I've joined two rings, the DinoLand Webring and the Paleo Ring.  The DinoLand Webring is up, but the Paleo Ring is still pending.  Also, I've added a link to the Official Dino Land Website.  Behind the scenes, I've begun work on an alphabetical genus list, for when you know the name of the animal you're looking for but not the classification.  This, however, will not be up for a while.

2-14-2000: Achillobator, a new large dromaeosaurid, was added.

2-11-2000: I've added another link, to the Science Museum of Minnesota.

2-8-2000:  Not much to report; two informally-named theropods, "Liassaurus" and "Merosaurus", which had previously escaped my attention, were added.

2-3-2000:  I've made a lot of minor changes to just about every page, and shifted some dinosaurs to different locations. 

2-1-2000:  I added two new genera: Cedarosaurus and Teyuwasu.  Also, I revised the Acanthopholis complex, cleaned up a lot of material, and revised some ages for some South American dinosaurs.  I expect to have them cleared up shortly.  I also worked on my personal page [deleted], added a rudimentary links page, and added this page.
