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

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

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)

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

Happy #FossilFriday. So excited to talk about #spinosaurids next week at #2024SVP meeting. Ever wondered how #Spinosaurus and its relatives fed? Stay tuned! Art by Dani Navarro

I have been working on a major tyrannosaur manuscript. Earlier this month it got approved with minor revisions and now it has been submitted for final decision. 🤞
