Shaken to hear Mark Norell passed—good friend, trusted colleague, giant in our field. Coincidentally I got the news as I was working on my talk for the Intl. Symp. on Asian Dinosaurs in Fukui. Here's my slide on Mark’s impact on Asian dinosaur science. It hurt to add 1957–2025.😢

A sad #FossilFriday with the news that legendary Mongolian dinosaur paleontologist Rinchen Barsbold passed away yesterday at the age of 90. I'm honored to have shaken his hand and more so to have coauthored with him twice, on Tarbosaurus and on Avimimus. R.I.P. Dr. Barsbold. 🦖

Excited to have this new #OA article out in @FossilsMDPI (doi.org/10.3390/fossil…), documenting the loss of cranial kinesis in phorusrhacid terror birds in connection with their remarkable hatchet-like feeding style. Dino Degrange ably led the project & we've got more on the way!

35 years ago day @SUEtheTrex (FMNH PR 2081) was discovered by Sue Hendrickson. Few dinosaur specimens are as impressive, and our team has had the privilege of studying the original fossils & CT scan data many times. As always, thanks go to the @FieldMuseum for their support! 🦖

Today is both #NationalKittenDay & #ThyreophoranThursday so here's another photo from when 8-week-old Pinky visited WitmerLab and shared a moment with Pinacosaurus. Also in attendance were Tarchia & a couple stegosaurs. #PinkysDinosaurAdventure

Since some folks on social media seemed a little freaked about yesterday's vid ⬇️ of me rolling these skulls out of the lab so the floors could be cleaned & waxed, I'll use #NationalSelfieDay as an opportunity to show you that all is well! They're all back with no mishaps! 🦖

#FossilFriday Getting the floors cleaned & waxed in all the lab spaces is no small task, which is why it hardly ever happens. I had to move out everything I possibly could. Also forced some decisions on what got moved to the dumpster. Kinda fun to see freshly waxed floors again!

Loved the #WalkingWithDinosaurs ep on Pachyrhinosaurus. Didn't do anything for the show but provided brain endocast viz for the #WWD book from our 2008 pub—bit.ly/4jTiNJf. Here's also our Hieronymus et al. article on centrosaurine facial skin—bit.ly/447xCC1.

Digging the new #WalkingWithDinosaurs on @PBS. Fun to see a 3D print of our T. rex brain endocast show up, plus a clip from a vid we did for a museum (youtube.com/watch?v=WcR2cs…). @KakapoJay at @BBC contacted me in 2023 for permission. 3D print your own here—skfb.ly/Mqsq

Happy #JurassicParkDay, marking the 32nd anniversary of the release of the original & arguably still the best film in the JP-JW series. It's a crazy world rn, so it's healthy to take some time to celebrate the silly. And yes, my vintage JP puppet also has a vintage JP puppet! 🦖

Every day is #DinosaurDay for us, but here's an old friend, a young Corythosaurus, flirting with that difficult transition to adulthood, showing its brain endocast & expanding airway & sinuses within its narial crest. Published w/ @DavidEvans_ROM in 2009: bit.ly/3kh7fRG

1998 was a still near the dawn of the digital revolution, so when I CT scanned this Edmontonia skull, I left with a big stack of film—no contrast adjustment, no 3D viz. But 27 years later, it's better than nothing when you gotta check out a feature or two. #FossilFriday

Really important review of dinosaur physiology out today led by @Stephanopteryx & @paleofox w/ @Ninjemys & @CrocJock80—bit.ly/43I1gxJ. Cool to see this old ankylosaur friend staring back at me as Figure 1, from a collab w/ former PhD students @Ninjemys & Ruger Porter.
