Something big is happening at the Sereno Fossil Lab. Stay tuned for tomorrow. #Dinosaurs #Paleontology

For #FossilFriday I’m pleased to announce our new paper on investigating the cranial performance and evolution of feeding behavior in tyrannosauroids and other theropods. Here’s a thread on some of our major findings. #Dinosaurs #Paleontology #Tyrannosaurus #Theropods

I just got word that my #tyrannosaur manuscript got accepted for publication. A huge thank you to my coauthors @eric-snively.bsky.social, Danny Barta, Paul Gignac, and Ryan Felice. #FossilFriday #Dinosaurs #Paleontology #Theropods

Had the pleasure of seeing a variety of spinosaurs at the Fukui Dinosaur Museum. #FossilFriday #Dinosaurs #Paleontology

In lieu of the recent #Nanotyrannus paper, here’s a couple of photos of me at the Burpee Museum of Natural History with Jane (Nanotyrannus lethaeus) and CMNH 7541 (Nanotyrannus lancensis), along with a flesh model of Jane by @tylerkeillor.bsky.social. #FossilFriday #Dinosaurs #Paleontology

Just in time for Halloween. Paul Sereno and colleagues have shown off two exceptionally well-preserved #Edmontosaurus mummies from the “Mummy Zone”. #dinosaurs #paleontology

Tune in tomorrow (1pm CT, 13:00 CDT), for an important paleo announcement from Dr. Paul Sereno (@paulserenoofficial) on Instagram. #Dinosaurs #Paleontology

Here's a T. Rex bored to death trying to bite their own tail. My partner asked me to animate it in stop motion, after she watched a video about the very important topic of "could T. Rex chew its own tail like a dog". The puppet is still a work in progress 🦖

Three #Tyrannosaurus skulls of @SUEtheTrex of @FieldMuseum, USNM 555000 of @NMNH, and Tufts Love rex of @burkemuseum. The skull differences in these three T.rex specimens is amazing! #dinosaurs #paleontology #FossilFriday

Decided to do a test run on @FEBioSoftware with the adult #Tyrannosaurus of @NMNH and #Raptorex (a juvenile tyrannosaur). Baby tyrannosaurs show high skull stress and low jaw muscle forces, compared to the adult condition. #FossilFriday #Dinosaurs #Paleontology

I decided to get my own copy of National Geographic’s Dinosaurs with spectacular #Spinosaurus artwork by Dani Navarro. #FossilFriday #Dinosaurs #Paleontology

Got a chance to see “Teen rex”, a new #Tyrannosaurus specimen, at the @denvermuseumns.bsky.social. It is a breathtaking specimen, I might add. #FossilFriday #Dinosaurs #Paleontology

Special thanks to Drs. Pat O’Connor & Dave Krause for hosting me at the @denvermuseumns.bsky.social collections. I had the pleasure of measuring various #Majungasaurus specimens and it is such an amazing theropod! Skeletal mount from Stony Brook University #FossilFriday #Dinosaurs #Paleontology

Since this year has proven to be the year of #Spinosaurus. Here’s a fantastic reconstruction by EdenBuster. I greatly adore the colors. #theropods #paleontology #dinosaurs

For #SpinosaurSaturday here’s #Spinosaurus and #Tyrannosaurus with neck muscle reconstructions. For my research, I’m looking at how much force the two theropods generated with moving their heads and necks. Big thanks to Eden Buster for helping with the reconstructions. #dinosaurs #paleontology

For #FossilFriday I’m pleased to announce that I’ll be presenting on #spinosaur feeding at @AnatomyOrg in Portland, OR on March 29. Come learn about spinosaur head and neck movements and feeding behavior. #AnatomyConnected #Anatomy25 #dinosaurs #paleontology (1/2)

I’m 30 years old now

Cats: Predators to Pets opens at the Field Museum tomorrow. I hope the story of how this exhibit came to be can one day be told because it is wild. For now, I think my colleagues' work speaks for itself! Also, this exhibit may just include a human-sized cat tree & a chance to pose with salad cat.

QRP with your skull art 💀 I do mine in 3d

Pleased to share our new paper studying the adaptive diversification of body shape in catfishes of the superfamily Doradoidea and exploration of the evolution of modularity and integration. DOI: doi.org/10.1643/i202... 50-day free access link: www.ichthyologyandherpetology.org/ihbjbd/bxi20...

What an amazing little kitty! A palaeontological dream come true - a three-week old sabertooth kitten was preserved in the Siberian permafrost. Surprisingly, even bleached by millenia in the soil, the fur is still a pretty dark brown. In life, it might have been nearly black.

Any word on when museums and other institutions will start having their accounts over here?

A new video in which I do something totally original for The Insider, criticse the accuracy of the Jurassic Park #dinosaurs (again): www.youtube.com/watch?v=3gwb...

Special thanks to @NicolasFechin and Carson Long for inviting me and Eric Snively of @OSUVertPaleo with consulting on a #Tyrannosaurus model of @suethetrex.bsky.social. #FossilFriday #Dinosaurs #Paleontology

There are so many of you joining right now that things may temporarily glitch! If you’re seeing “invalid handle”, this is probably one of those things — see this thread for more information.

Yep, I'm joining the migration too. Fans of #dinosaurs #paleonotlogy etc. I am here now.

Phylogenetics is famous now 🧪

I took this photo a couple years ago and it's still my luckiest great blue heron capture. #birds

For the young scientists in your lives, check out the latest from National Geographic. 5 Minute Dinosaur Stories! Like a book of fairy tales...stories of real dinosaurs going about their lives, informed by fossils, facts checked by yours truly!

When Harley Garbani found this T. rex skull in 1966, it was the first adult rex uncovered in 58 years. “I didn’t figure another of those suckers would ever be found” Garbani reportedly said. I like the graphic design on the 1981 case.

My PhD student Guilherme Hermanson & I have a new paper out today in Ecology & Evolution! 🐢🤩 We think the morphologically conservative body plan of turtles can in part be explained by allometric constraints imposed by the shell. Thread 👇 for some highlights onlinelibrary.wiley.com/doi/10.1002/...

The Anatomy of a Borb. By fluffing up their feathers, they trap tiny pockets of air close to their bodies, which acts as insulation. Helping them regulate their temperature.

More progress on the #Re-otyrannus #Eotyrannus skeletal "update", going smoothly in between work and other projects.

Anatomy lesson: the pointy bit at the top of the skull is where the chomp muscles attach. If you have a dog, pet their head and feel for this ridge. The higher the ridge, the bigger the muscles. Think how powerful your pup’s chomp is. Then look at this picture and appreciate how scary these guys are

I don't have anything new to offer up as a distraction, but maybe something older might help someone? Here's a video all about the spotty history of fossil jacketing. We got to go hang out at a real dig for it. Hopefully it can take your mind off things. If you need that. youtu.be/8eECVzpzkeI

Can I take a moment to comment on how unique the skeletal morphology of #spinosaurids are? Theropods with relatively greater head and neck lengths than other #theropods. Artwork by @skeletaldrawing.bsky.social
