New article out today in @AnatRecord led by @Don_Cerio based on his dissertation work here: https://t.co/m32763jtEY. Orbital soft tissues—especially the eyeball—have been difficult to study, constrain, & quantify. We hope this croc study is a step forward. Well done, Don! 🐊👁️👀

My parents took me to @ROMtoronto—my 1st dinosaur museum!—when I was a kid. Pic 1 is @SeishiroTada & me last night. Pic 2 was one I took ~50 yrs ago.

Parasaurolophus (ROM 768) was named 100 years ago (Parks 1922) & is now one of my study species. Livin' the dream! #2022SVP

#FossilFriday Had to dig out some old data on the pterosaur Anhanguera, reminding me of our now ancient 2003 @Nature article on pterosaur brain endocasts—https://t.co/ZI1LTxe1lP. Here's some fresh 3D viz plus the cover art by Kyle McQuilkin & Ryan Ridgely that Nature didn't use.

Cary Woodruff (@DoubleBeam) was a great leader on this project! We also had two veterinarians—Ewan Wolff (also a paleopathologist) & Sophie Dennison (imaging specialist), plus Matt Wedel (sauropod air sac expert, @SV_POW ). I'm proud to have been included! https://t.co/4SxiK3uX0N

Floating crocs... Wegner (1958) suggested paranasal air sinuses helped croc heads float. In 1997, I said, "I dunno, dude..." (https://t.co/rCWrSWTlvQ, p. 58).

Now @GatorsDaily shows floating croc heads

@Ninjemys @RoyalTyrrell Thanks for chiming in, Jason (@Ninjemys). I'd indeed like to think that the antorbital fenestra and its function has been pretty well understood for almost 25 years (https://t.co/rCWrSWTlvQ—there's even RTMP specimens!)...altho' there's always more work to be done.

Thrilled to have this new article in @AnatRecord out today! Aetosaur brain endocasts w/ great collaborators led by Belén von Baczko & Julia Desojo. #Paleoart by @victorleshyk

Ryan Ridgely & I first scanned these @ucmpberkeley fossils many yrs ago—glad to finally get this out!

Again, turkeys provided supporting information to help us understand extinct dinosaurs, in this case a project on the dorsotemporal fenestra started by @CrocHolliday when a PhD student here. Holliday, Porter, Vliet, & Witmer (2020): https://t.co/jI3sOdvylG. @BrianEngh_Art 5/12

Cool how an innocuous post 2 yrs ago prompted @Dave_Hone to contact me & then lead a great project with @Jordan_Mallon & @thepatrick_h on gharial sexual dimorphism—out today: https://t.co/TAXcbcdmsk. Also a chance to publish some croc sinus viz!

It's Homecoming Weekend here at @OhioU and @CityofAthensOH! We're the #OHIOBobcats, so why not sneak a little science into the #OHIOHC2019 festivities? Check out our Visible Interactive Bobcat site for more goodies—https://t.co/liuYaqG3IS—thanks to @hyaenaDon Cerio! @OHIOAlumni
