What's New

    This page will be used to tell what major changes have taken place, or what new taxa have been added.  I'm not going to bore you with reporting minor typographical changes, though, unless there's a huge volume of them.  For updates from 2000-2004, check this archive page.  If you'd like to know where I got some information, please contact me!
    Since I don't usually post changes of classification, and I don't redo the entries on these update pages, you may run into cases where a name is no longer on the page I originally posted it at.  In such cases, the alphabetical index is your friend, hopefully.

5-8-2008: In a bit of a hurry, as in a short time I will be unable to publish updates until August (and I may be at a new address anyway); however, I do have two new dinosaurs from the LK of Argentina: Macrogryphosaurus gondwanicus, a basal iguanodontian, and Muyelensaurus pecheni, a titanosaur.

4-21-2008: Having a bit a trouble with updating, but we can still have fun with iguanodonts.  There's a new species of Camptosaurus, C. aphanoecetes, for the Dinosaur National Monument specimens, and a new listing for C. depressus, as Planicoxa depressa.

4-5-2008: In the "oh, yeah, I can put those up now" department, we have old/new iguanodonts Dakotadon lakotaensis (EK of South Dakota, formerly Iguanodon lakotaensis) and Dollodon bampingi (EK of Belgium, formerly the "I. mantelli" gracile Bernissart iguanodont), and LTr British Asylosaurus yalensis (formerly "those Thecodontosaurus bones at Yale").

3-1-2008: On the heels of finally switching to Richardoestesia, I made some overdue additions, adding Razanandrongobe sakalavae, a possible theropod from the MJ of Madagascar, and Suchosaurus cultridens and girardi, two probable spinosaurids from the EK of Europe.

2-26-2008: "Diceratops" and "Microceratops" have received new names, Diceratus and Microceratus respectively.  I also fixed the age of Cryolophosaurus, and, uh, yeah, and Ricardoestesia was revised to Richardoestesia. 

2-11-2008: Slow January, and then in the first couple of weeks of February we get a lot of new information.  There's possibly the last name from 2007, Chinese EK ankylosaurid Crichtonsaurus benxiensis, and a quartet to usher in 2008: carcharodontosaurid Eocarcharia dinops and abelisaurid Kryptops palaios, both from the EK of Niger; and lambeosaurine Sahaliyania elunchunorum and hadrosaurine Wulagasaurus dongi, both from the LK of China.  I also split Caenagnathus from Chirostenotes.  As usual, I'm also sitting on a couple of things.

12-26-2007: Now for an experiment: I updated with EK Chinese basal titanosauriform Dongbeititan dongi.  Updates often equal "new name or new information appears almost instantly after I update, which I then sit on a few days before adding."  Does it work this time, too?  

12-16-2007: The new JVP brings forth Velafrons coahuilensis, a new lambeosaurine from the LK of Mexico; Carcharodontosaurus iguidensis, from the early LK of Niger; and new information on Styracosaurus. 

12-9-2007: Glacialisaurus hammeri, an EJ Antarctic sauropodomorph, has been added.  Additionally, I finally added the seven genera from Pakistan that first came to wide attention this spring.  Frankly, I'm not sure what to make of them, and the sauropods are classified under an odd arrangement of "Balochisauridae (saltasaurid)" and "Pakisauridae (titanosaurid)", but here they are: ?titanosaurian sauropods Balochisaurus malkani, Brohisaurus kirthari, Khetranisaurus barkhani, Marisaurus jeffi, Pakisaurus balochistani, and Sulaimanisaurus gingerichi, all LK except for the LJ Brohisaurus; and Vitakridrinda sulaimani, an LK abelisaurid.  I don't have much to say (yet), so they are slim entries.  
I do know about recent work on iguanodonts, but it's a preprint, so I'm waiting. 

11-18-2007: It's been interesting for weird sauropods as of late.  We have the bizarre new Xenoposeidon proneneukos from the EK of England and new information on Nigersaurus and its distorted, "Persistance of Memory"-esque skull.  On the ornithischian side of the aisle, Craspedodon may not be the inoffensive iguanodontian it was long thought to be.  

11-2-2007: Since I was around and had some time, I decided to skip the long update gap and added the two new EJ Indian sauropodomorphs, little Pradhania gracilis and big Lamplughsaura dharmaramensis.

10-31-2007: As intended back on the 18th, I reorganized the neotheropods and basal tetanurans (thanks for the Cryolophosaurus article help, Marcel!).

10-18-2007: Some new stuff: the LK hadrosaurid from Utah, Gryposaurus monumentensis, plus a redo of Hadrosauridae; new LK Chinese dromaeosaurid Luanchuanraptor henanensis; and LK Albertan ceratopine  Eotriceratops xerinsularis.  There are also new data on Cryolophosaurus and fellow basal theropods, but I don't have the paper.  Also, I should really revise the ages for the Dinosaur Park/Horseshoe Canyon animals at some point.  Plus, I'm a coauthor on a description of a new Arctic Cretaceous sponge.

10-3-2007: Mostly updates to the base of the ornithischian tree this time; Thescelosaurus! is eight years old this month (about a week from now, actually), and there was some stuff there that apparently hadn't been adjusted the whole time.  Anyway, the line between basal ornithopod and non-ornithopod is getting fuzzier and fuzzier, so there may certainly be inconsistencies.

9-21-2007: Too many new things, too little time.  This time around, there's LK Argentine alvarezsaurid Achillesaurus manazzonei, EJ Moroccan abelisauroid Berberosaurus liassicus, and LK North American leptoceratopid Cerasinops hodgkissi. 

9-12-2007: I was actually trying to upload all through August, but was having problems.  Therefore, there's another backlog.  We have EK Texan "brachiosaur" Paluxysaurus jonesi, giant LK Argentine titanosaurian Futalognkosaurus dukei, LK Chinese basal lambeosaurine Nanningosaurus dashiensis, EK Chinese large basal therizinosaurian Suzhousaurus megatherioides, tiny LK Mongolian basal dromaeosaurid Mahakala omnogovae, and new species Yunnanosaurus youngi (first Middle Jurassic "prosauropod").

7-29-2007: Fell a bit behind; we've got new sauropods in Amargatitanis macni and Nopscaspondylus alarconensis (LK of Argentina), stegosaur Jiangjunosaurus junggarensis (LJ of China), nodosaurids Zhejiangosaurus lishuiensis (LK of China) and Zhongyuansaurus luoyangensis (K of China), and giant hadrosaurid Zhuchengosaurus maximus (EK-LK boundary of China).

7-21-2007: Lagerpeton-like basal dinosauromorph Dromomeron romeri, from the LTr of New Mexico and other scenic southwestern points, has been added. 

7-3-2007: Not a whole lot going on, just some more hadrosaur tidying, and an update to the Theropod Database link.

6-16-2007: So, yeah, a bunch of new names came down the pipe just as I was making the last update.  You get Eocursor parvus, the most-completely known Triassic ornithischian (and some rejiggering of basal Ornithischia), a new species of Psittacosaurus (P. major), Gigantoraptor erlianensis, a new giant basal oviraptorid from the LK of China, consolidation in favor of Majungasaurus and Kritosaurus, some work on the Lambeosaurinae tree, and updates to the Fauna page, including the Lower Elliot Formation and Kirtland Formation.

6-10-2007: Huanghetitan ruyangensis, a macronarian sauropod from the K of China with a really deep chest, has been added.  Also, note that the Theropod Database is currently off-line.

5-28-2007: Australodocus bohetii, a new Tendaguru diplodocine, and Aeolosaurus colhuehuapensis, a new species of the saltasaurid Aeolosaurus, were added.

4-8-2007: It was a week or so ago that everyone else noticed, but Aniksosaurus darwini has been published, and I revamped basal Sauropodomorpha and Dromaeosauridae.  Oh, and Krzyzanowskisaurus and Azendohsaurus have been cast out.

3-29-2007: Pantydraco caducus, a new name for Thecodontosaurus caducus, was added, and I tweaked Archaeopteryx.

3-22-2007: The "burrowing hypsilophodont", Oryctodromeus cubicularis, has been added.  Go hypsilophodonts!

3-18-2007: Beware the...St. Patrick's Day?  Four new theropods came to my attention yesterday: Lophostropheus airelensis, a new name for Liliensternus airelensis; Sinocalliopteryx gigas, a large Yixian compsognathid; Shanag ashile, a dromaeosaurid from the EK of Mongolia; and Urbacodon itemirensis, a troodontid from the Cenomanian (LK) of Uzbekistan.

2-25-2007: Albertaceratops nesmoi, a new centrosaurine with long brow horns, has been published, and Chingshakiangosaurus has been updated.  

1-27-2007: I changed Chasmosaurinae back to Ceratopinae.

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 Ceratopinae 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 ceratopian 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 neoceratopian 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 ceratopian), 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.

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 ceratopian of Thescelosaurus!; a new assessment of "Morosaurus" agilis; new EK Chinese basal neoceratopian 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.  

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.

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.
