Qianosuchus, a.k.a: Spinosaurus but cool a VERY long, muscular tail (often not seen in art!), giant shoulder girdles and scleral rings, numerous diminute osteoderms, an overall amazing insight into poposauroid evolution, specimens exquisitely preserved! A one-of-a-kind animal

Pedeticosaurus! a cute lil very complete guy, with an anatomy that nicely fits inside the direct croc ancestry line!

Otodus megalodon #paleoart commission!! (definitely not a generalized ginormous lamniform) i love how silly sharks look

Iranotherium :P

Doswellia kaltenbachi! the boxy, pancaked armoured scarf dragon probably my hardest/most rigurous skeletal out there, but deserved, since its bones are so well measured and documented (for @cascoclauda.bsky.social :P )

Somewhere in North Africa. 95 million years ago. A male Spinosaurus aegyptiacus, rejected by the females of his own species. A female Spinosaurus mirabilis, wandering far from home. She is impressed by his great size. He finds unexpected love. Life finds a way.

Why is bro holding back its face skin with a clothespin just loook at those eyes

El 'taco (psittacosaurus art commission :3)

i love seeing monitor lizards swim yesssss go my brave mosasaur cousins you're doing them proud!! www.youtube.com/watch?v=Y0nO...

Smallest known rauisuchian-grade critter!! (not a crocodylomorph)

Say hi to my son he is an unicelular lifeform with an IQ of 2 and his diet consists of sand

happy #fossilfriday! bonus: this is diamantinasaurus, a titanosaur from late cretaceous australia. in 2025, it became the first sauropod to have fossilised gut contents described, providing evidence of bulk feeding and multi-level browsing behaviour (art by @chrisdipiazza.bsky.social)

gonna tell my kids this was ptychotherates

Took a while to put up the scans together but here is the critter! For some reason it has musculoskeletal adaptations for a really strong bite despite its tiny size, specially a big surangular fossa for the *adductor mandibulae externus* muscle! (that which today gives modern crocs their "cheeks")

Gotta love how they represented the pathologic metatarsal bitemarks as its buddy being a fucking asshole for no reason lol

Did you know that while Allosaurus and Apatosaurus explored eachother's bodies in the Morrison Formation, small, bipedal, omnivorous crocodylomorphs with spoon-like jaws were running around on the forest's floor?

"HEY, CALM DOWN! this is NOT you!"

Leedsichthys problematicus, a whale-sized filterfeedeer pachycormid fish from the late jurassic I dont know much about non-tetrapod anatomy, so below i'll thank everyone who coached me and helped me make this commission accurate within what we know of it !! ↓↓

happy #fossilfriday! bonus: is caipirasuchus, a notosuchian from late cretaceous brazil. the species c. catanduvensis was described by iori et al. in 2024, and its palate suggests that it may have been a social animal that relied on vocalisations for communication (art by rodolfo nogueira)

until 2012, the clade cetotheriidae was thought to be extinct. that year, a paper by fordyce and marx suggested that the pygmy right whale is a cetothere, and a 2023 genomic study by dutoit et al. supports this conclusion pmc.ncbi.nlm.nih.gov/articles/PMC... onlinelibrary.wiley.com/doi/10.1111/...

happy #fossilfriday! this is cetotherium, a small baleen whale that lived between the miocene and pliocene. c. riabinini is notable for being one of the smallest whales in the fossil record, being only around three metres in length (life reconstruction by nixillustration)

Say goodbye to bipedal Saltoposuchus in 1921, the ulna was mistaken as an overly long metatarsal due to being slightly flattened (likely taphonomically) *and* the tiny hand led to the assumption of small forelimbs Seems to have stuck for more than a century

i jumped and squeaked and peed a little

Terrestrisuchus, the vertebrate version of a stickbug, the most unserious animal ever, my stupid son that i love related to the ancestry of modern crocodiles

happy easter from incisivosaurus, a small oviraptorosaur from early cretaceous china best-known for its large, rabbit-like front teeth 🐇 this dinosaur could pull double duty as easter egg producer and the easter bunny (art by @literallymiguel.bsky.social)

happy #fossilfriday! this is pezosiren, a sirenian from early eocene jamaica. a basal relative of manatees and dugongs, pezosiren was able to walk on land, and may have had an amphibious lifestyle like a hippopotamus (art by joschua knuppe)

The name of this guy is concerningly close to "Ass crocodile" in spanish

Speculative primitive spinosaurid inspired by megalosaurids and Monolophosaurus Colors based in Potamites montanicola suggested by my friend @cascoclauda.bsky.social as usual c: #paleoart for @edgescience.bsky.social !!

Guys the skull of Orthosuchus is super squished pls dont take its lateral view drawing at face value it would look more like a longer-snouted protosuchus lol

wow! a new study by glup and shitto has recovered the alleged mexican tyrannosaur labocania aguillonae as a giant early palaeognath with teeth, hereby renamed labokiwi aguillonae! mind-blowing stuff 🤯🦖 doi.org/10.1016/j.oneear.2025.101314 (art by @hodarinundu.bsky.social)

holy shittttt ARCHOSAURIA WAS ANCESTRALLY FUZZY "Exquisite integument preservation of a triassic stem-archosaur reveals valuable insight in the origin and evolution of feathers" (2025): doi.org/10.48550/arXiv.2204.06826

happy #transdayofvisibility! being trans is far from unique to humans; for example, this is zuri, a lioness who grew a mane and took on masculine behaviour's following the death of their mate 🏳️‍⚧️🦁 www.discovermagazine.com/its-rare-but...

Notice how the slit pupil automatically re-orients itself to be perpendicular with the floor

gator skeletal in comparison to crocodiles, alligators have proportionally larger limbs and girdles, and more distal caudal vertebrae

When they make Php: 2Ice 2age and deinotherium realizes he still isn't being addressed

a semiaquatic lifestyle for the proboscidean moeritherium appears to be confirmed by a new study on its enamel microwear by semprebon, sanders, and uttecht 🐘 vindicating its portrayal in 'walking with beasts' almost 25 years ago www.sciencedirect.com/science/arti...

Its a privilege but also a curse

bringing this from my twitter but is there ANY other character that rivals the ratio of gay-porn-to-screen-time of that one fuckass yellow dog that appeared for like 2 seconds in the background of the latest TADC episode

Protosuchus a lil guy that pretty much posseses a 1-to-1 anatomy to that of how a late-triassic crocodilian direct ancestor would have looked like :P

happy #fossilfriday! bonus: this is chilotherium, a rhino that lived in africa and eurasia during the miocene and pliocene. a hornless rhino, male chilotherium competed for females by using their prominent, tusk-like second incisors in combat (art by @mariolanzas.bsky.social)

happy #fossilfriday! this is shringasaurus, an archosauromorph from middle triassic india. its robust neck and shoulder musculature indicates that it used its distinctive horns for intraspecific combat (art by @literallymiguel.bsky.social)

Art commission for @hekersobek.bsky.social!!

happy #fossilfriday! this is lisowicia, a dicynodont from late triassic poland. i have discussed this one before, but my previous coverage was not very comprehensive, and i can’t allow that to stand as a lisowicia superfan so strap in (art by sarah barrett)
