It’s finally out! Our work addressing the origins of reptiles is published in PCJ! peercommunityjournal.org/articles/10.... We use novel info gleaned from the scan data of dozens of stem reptiles to substantially revise our understanding of early reptile evolution #paleontology #herpetology
A great float of Attenborosaurus swiftly navigate their pelagic environment in their hunt for fish. Attenborosaurus (named after Sir David Attenborough) is an extinct marine reptile that existed during the early Jurassic, it was a primitive pliosaurid, closer related to short-necked plesiosaurs.

It's #Tylosaurus Tuesday my dudes! Every now and then we find some baby mosasaurs in Kansas that don't quite make it very long in life. A lucky few of them don't end up as shark puke either. Here are 2 premaxilla snoots, the left one from Clidastes and the right from Tylosaurus with a little prow 🧪

Scales being found only on the flippers here immediately brings to mind cetaceans that roughen and thicken the leading edge of their fins & flippers for hydrodynamic purposes.
Sven Sachs@dinosven.bsky.social · last yr.🚨 Big plesiosaur news 🚨 Our paper is out. We describe pigment cells and scales in a Jurassic plesiosaur. Small scales are found at the limbs which enforced them. Body and tail are scale-less. Many thanks to lead-author Miguel Marx & the team. www.cell.com/current-biol... #Science #News #Nature 1/3
Blue whales make among the loudest calls of anything in the ocean... but killer whales cannot hear them at all because their calls are so deep. In my new paper I suggest this is an adaptation to reduce killer whale attacks. onlinelibrary.wiley.com/doi/10.1111/...

Who owns the 'facts' on the #LochNessMonster and are believers right to be super-aggressive towards the sceptics? New #TetZoo article now has a good number of comments .... tetzoo.com/blog/2024/11... #LochNess #Nessie

Come by B66 in the poster session this afternoon for Best Practices for Fossil Vertebrate Skeletal Diagrams by @skeletaldrawing.bsky.social and myself! #2024SVP
Happy #FossilFriday everyone! Excited to share that very soon, I will be able to share a piece of research that I've been hard at work for years. Not sure if it will release today, but figured I would share a little teaser here...
Hello new Bluesky followers- enjoy some Mosasaurus reconstructions. I tried to incorporate the clavicles and interclavicles into these reconstructions, as well as a shallower chest due to lizardy swept-back ribs.
Trying to think of a skeletal to share that I haven't really discussed elsewhere, so here's my take on the skeleton of everyone's favorite giant flying reptile, Quetzalcoatlus. The 2021 monograph by Padian, et al. made this worth tackling.
Hello lovely folks, I will try to be more active here now considering how many bad decisions are made in the other place. Have some recent images from the streams.
Over on Twitter, I've been doing a thing called TetZoocryptomegathread, where I discuss the twists and turns pertaining to given pieces of 'monster' evidence, usually photos. They've been hugely popular. As an experiment, let's see how they fare here. Fingers crossed. Here we go...
Guanlingsaurus, my skeletal restoration of this giant ichthyosaur. A short, toothless snout, high vertebral count, and reduced ossification acrodd the skeleton make this a very unique animal

Man I haven’t posted on here in a while- here’s a currently unfinished painting of the supremely weird Sclerocormus
I did skeletal and some other illustration work for a new publication by Dr. Andrzej Wolniewicz et al., publishing a new of saurosphargid and a new scheme for sauropterygian evolution. Give it a read! https://elifesciences.org/articles/83163
Hello everyone! For anyone who didn’t know me before, I’m a paleontologist who studies intraspecific variation to understand vertebrate evolution. I’m currently a postdoctoral researcher at NC State on the Dueling Dinosaurs project studying the evolution and growth of tyrannosaurid dinosaurs.

I rarely draw dinosaurs, but here’s a Corythosaurus
