It's been far too long since Tylosaurus news...so here's another NEW TYLOSAURUS PAPER! 🦎 From me & Mike² (Everhart & Polcyn) For the first time in over 150 years, the holotype of Tylosaurus proriger is fully described & figured in detail. Incredible artwork by Andrey Atuchin

Our paper on turtle origins is finally out in Current Biology, with two major implications for our understanding of reptile evolution 🐢 #Paleontology #Turtles #Evolution www.cell.com/current-biol...

Last year I started a series of dinosaur line-arts, four species per paper sheet. This is first batch: Compsognathus longipes (based on German specimen), Sinoceratops zhuchengensis, Maiasaura peeblesorum and Hypsilophodon foxii. Done with black ballpoint pen. #paleoart

Asiatyrannus xui (or, according to the latest research, Tarbosaurus juvenile) from last year. This specimen was found in same formation with long-snouted Qianzhousaurus. Initially it was described as distinct small-ish taxon. Paint 3D. #paleoart #dinosaur

New paper just dropped finally describing a complete specimen of Dakosaurus maximus and what a beauty it is. Some highlights, in addition to this being a long time coming, is the presence of bitemarks on the face and chondrichthyan material in the stomach doi.org/10.26879/1577

Apatosaurus louisae #paleoart #dinosaur #jurassic #apatosaurus

Another obligatory New Year art. 🙂 Since 2026 is the Year of the Horse, I decided to choose one of the many extinct horse species. This is Mesohippus bairdi, which lived during the Early Oligocene in North America. Happy holidays! #happynewyear2016 #yearofhorse

A charging Tarbosaurus bataar. I painted this piece as an exercise in fullbody black and white art without lines. As usual, I used various brushes. I also practiced painting the ground kicked up by the animal's feet. #paleoart #dinosaur

Daspletosaurus torosus, a type species of its genus, from the Late Cretaceous (Campanian) of Alberta, Canada. The holotype was found in the Oldman Formation in 1921. Daspletosaurus had relatively long forelimbs for a tyrannosaurid and quite massive build. #paleoart #dinosaur

Long-snouted tyrannosaurid Qianzhousaurus sinensis attacks high-crested oviraptorid Corythoraptor jacobsi. Qianzhousaurus belongs to Alioramini, a clade of gracile tyrannosaurid with probable preference to small and agile prey. Late Cretaceous of China. #paleoart #dinosaurs

The Tyrannosaurus rex is moving away from the viewer to the left. I started this drawing spontaneously and without references, and then adjusted the proportions. I'm not very happy with the position of the right leg, and the shading is a bit sloppy. #paleoart #dinosaur #trex

Painting of the front half of Giganotosaurus carolinii, a large carcharodontosaur from the Late Cretaceous of Argentina. It was among the largest theropods ever existed and rivaled big T. rex specimens in size. #paleoart #dinosaur #giganotosaurus

A portrait sketch of Cryolophosaurus elliotti, a remarkable theropod from the Early Jurassic of Antarctica. This dinosaur is known for its tuft-shaped crest, positioned above the eyes. It was given informal name "Elvisaurus" due this feature. #paleoart #dinosaur #jurassic

A sketch of a Tyrannosaurus rex pulling at the hide of its prey. The front upper teeth of tyrannosaurids were D-shaped in cross-section and used for carving and scraping meat from bones. Some dinosaur bones even bear teeth marks left by this behavior. #paleoart #dinosaur #tyrannosaurus #trex

Portrait of hadrosauroid Cariocecus bocagei from Early Cretaceous of Portugal. It's known by partial articulated skull from Papo Seco Formation. Cariocecus had low head profile, without crests or bulbous nose. Done in Krita. #paleoart #dinosaur

Portrait of Torvosaurus tanneri, big megalosaurid theropod from Morrison formation. It was massive predator which coexisted with array of other theropods, including smaller megalosauroid Marshosaurus. Done as experiment with style. #paleoart #dinosaur

Adding to the collection of theropods with weird hands described this year. Duonychus, Mexidracon and the already posted Manipulonyx.

Manipuloyx, a new alvarezsaur with really fascinating hands! The condition of the fingers isn't that unusual for the clade but the OSTEODERMS on the hand are new!

New research on juvenile Redondasaurus fossils from Chinle Fm. reveals that immature phytosaurs show a mosaic of traits seen in both early and late-diverging species. Links b/w growth & morphological evolution in Phytosauria. Goldsmith & Stocker: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Chindesaurus bryansmalli, a basal predatory dinosaur from the Late Triassic of Arizona. Its holotype, a partial postcranial skeleton, was nicknamed "Gertie". Chindesaurus was classified as herrerasaurid, but recent analyzes recovered it as Tawa hallae relative. #paleoart

Monochrome portrait of Saurornitholestes langstoni, a dromaeosaurid from the Late Cretaceous of North America. It's known by many fossils, including almost complete skeleton. The relatively boxy skull of this specimen was described in 2019. Keratinous snout tip is speculative. #paleoart

Yawning Prognathodon overtoni for friends's Birthday. Prognathodon is a genus with a complex taxonomy. Some of its species have been reclassified as separate genera, while others are the opposite, such as this one, previously known as Brachysaurana. Done in Paint Tool Sai 2.0. #paleoart

A portrait of Khankhuuluu mongoliensis (or "Mongolian dragon prince"), a tyrannosauroid from the Bayanshiree Formation. Its remains were previously described as belonging to Alectrosaurus, but are now classified as a separate genus. Done in Paint 3D. #paleoart #dinosaur

Just in time for spooky season: DINOSAUR "MUMMIES!" Unlike Egyptian mummies, these don't have squishy bits preserved, but the rock around these carcasses had clay capturing texture of scales, a midline crest w/ keratin spikes, &, brand new, feet w/ hooves! 🧪⚒️🦕🦖 www.science.org/doi/10.1126/...

Dire wolf/wolves by Mark Hallett. Had no idea the pack hunt drawing at the bottom right was a thing, so this was a pleasant surprise.

Papiliomaris kluessendorfae, first reported in 1985 as the Waukesha "Butterfly Animal", was recently described as a strange bivalved arthropod with three pairs of large, feathery appendages. Some reports indicate it could reach up to 20cm wide.

Portrait of Tameryraptor markgrafi, a carcharodontosaurid from the Late Cretaceous of Bahariya Formation (Egypt). Its remains have long been attributed to Carcharodontosaurus, but it is distinguished by the presence of a small horn on its nose and symmetrical teeth. #paleoart #dinosaur

An adult Ceratosaurus nasicornis caught juvenile Torvosaurus tanneri. These theropods, like an Allosaurus, were found in the famous Morrison Formation, but their remains are much less common. Despite some differences in food sources, they competed and killed each other from time to time. #paleoart

A happy day 2 of #Croctober (lets see how long I can keep this going) Crocs are well known for their parenting, but did you know that we even have fossils of them on their nest? This specimen comes from Germany and clearly shows a Diplocynodon mother that died on her nest

Portrait of dinosauromorph Pisanosaurus mertii from the Late Triassic of Argentina. It was either basal ornithishian (as classified initially) or silesaurid. In any case this animal was herbivore or omnivore a little more than a meter long. Neck filaments are speculative. #paleoart #dinosaur

News @ Urwelt-Museum Oberfranken (UMO) in Bayreuth: new ichthyosaur, Eurhinosaurus mistelgauensis, named today after UMO's prime excavation site, the Jurassic clay pit Mistelgau. @olorotitan.bsky.social beautifully reconstructed the to-be fossil on a belemnite battleground typical for the locality.

The big tableau of early Permian synapsids in the next gallery unified a bunch of mounted skeletons that had previously been in separate cases. A nearby lab area covered the concept of extinction ("the fate of all species") in general terms.

Croc fans simply can't catch a break, after Kostensuchus in late August and Paarthurnax just a week ago we got ANOTHER fossil croc published Meet Thikarisuchus, a very small neosuchian from the Cenomanian of Montana

A megaraptoran skeleton! From the end of the Cretaceous! Excited about the announcement of Joaquinraptor, the top predator down south when tyrannosaurs ruled the north. The Schwarzengger to T. rex's DeVito (at least in the arms category). My thoughts: www.livescience.com/animals/dino...

Duonychus tsogtbaatari, a therizinosaurid from the Late Cretaceous of Bayanshiree Formation (Mongolia). It's known by partial postcranial skeleton including dorsal vertebrae and both forelimbs. Duonychus has only two manual digits, with big and curved claws. #paleoart #dinosaur

Prognathodon currii swimming near small Enchodus pack. Art was inspired by some Pseudorca photoes. #paleoart #mosasaur #prognathodon #mesozoic

#ZAVACEPHALE IS FINALLY OUT! 🥳 Our first definitive Early Cretaceous pachycephalosaur! (~15 my older than the previous oldest pachycephalosaurs) And the first hand material for the clade! I can't tell y'all how much of a pleasure it was to review this paper! ☺️

Portrait of Riparovenator milnerae, a baryonychine spinosaurid from Early Cretaceous of Isle of Wight. Remains of this theropod previously were assigned to Baryonyx. In this work I painted color on a black base - an unusual experience! Done in Adobe Photoshop. #paleoart #dinosaur

Colored portrait sketch of Troodon formosus, a troodontid theropod from the Late Cretaceous of USA and Canada. It was initially described by tooth as a lizard and then referred to pachycephalosaurids. Later it became clear that Troodon was a bird-like theropod. #paleoart #dinosaur

Today I downloaded Gimp and did some work in it. It was a lot of fun using the different tools! The result was this portrait of a random megaraptoran. Megaraptora is a clade of possible coelurosaurs (or even tyrannosauroideans) with forelimbs adapted for capture of prey. #paleoart

Croc fans are eating good today, we just got a new and exceptionally well preserved robust peirosaurid from Patagonia: Kostensuchus atrox We have most of the skeleton, which suggests a total length of perhaps up to 3.5 meters

Hi all, me, @richardjbutler.bsky.social and the amazing UK-US-Moroccan team are delighted to announce that.. we have a new specimen of Spicomellus AND IT'S WAY WEIRDER AND WAY COOLER THAN WE EVER IMAGINED!!

Mammut americanum, the elephants relative #art #paleoart

Want some theropod legs? 🙂 New work in progress.

More crocodylomorph critters: Sphenosuchus - the one that started it all Pattisaura - from this year! (do NOT misgender her) Dibothrosuchus - wide-headed chinese boy Litargosuchus - PATHETIC creature.... we must protect,.
