Been working on a range of motion study with Alexandre Fonseca for #FossilFriday. Really enjoying the sense of scale with the head and neck of #Suchomimus, #Tyrannosaurus, and #Spinosaurus. #Dinosaurs #Paleontology

SVP poster accepted. Looking forward to talking about how bizarre and unique spinosaurids are compared to other theropods and other extant animals. 😉 #Spinosaurus #Dinosaurs #Paleontology #SVP2026 #2026SVP

In 2022, I was a summer fellow at the @NMNH. I was interested in scanning some of the theropods on display and in collections. For #FossilFriday, here are the skulls of Allosaurus (USNM 4734) & Tyrannosaurus (USNM 555000). #Dinosaurs #Paleontology

For #FossilFriday, I thought I’d show off the skulls of #Postosuchus along with #Tyrannosaurus, #Spinosaurus mirabilis, and #Carcharodontosaurus. Unlike living crocodylians, Postosuchcus’ skull is relatively tall like that of a theropod 🤔. #Dinosaurs #Paleontology

Big thank you to Alexandre Fonseca and Ulises Jose Sosa for digitally processing & helping with articulating the cervicals of #Spinosaurus, #Suchomimus, and #Tyrannosaurus for a range of motion study. #Theropods #Dinosaurs #Paleontology #FossilFriday

Articulated #Suchomimus skull and neck. Suchomimus was a massive spinosaurid from West Africa. The elongated jaws and hypertrophied neck suggest it would have engaged in rapid movements of the head and neck. Perfect for capturing fish. #FossilFriday #Dinosaurs #Paleontology

Oh wow. SVP will be in Chicago next year.

Tune in tomorrow at @paulserenoofficial on Instagram. #Dinosaurs #Paleontology.

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

I would like to thank my coauthors @eric-snively.bsky.social, Danny Barta, Paul Gignac, Ryan Felice for their collective effort in this research project, the advice and feedback of @histo-holly.bsky.social and paleo students/staff of OSUMedicine, the reviewers and @anatrecord.bsky.social.

The phylogenetic results show that the groups Tyrannosauroidea, Abelisauridae, and Allosauroidea have relatively lower cranial stress magnitudes than megalosauroids and maniraptoriformes.

Upon examining the compressive and tensile stress of the theropod crania, we consistently see tyrannosaurs display low compressive stress when biting and low tensile stress when opening their jaws.

Deep-snouted tyrannosauroids show lower cranial stress than the slender-snouted alioramins and small early tyrannosaurs which have high cranial stress.

Non-tyrannosauroid coelurosaurian theropods like dromaeosaurids, compsognathids, and megaraptorans show varying cranial stress magnitudes.

Non-tyrannosauroid theropods show varying levels of cranial stress such as short-snouted abelisaurs, allosauroids, and early theropods having low stress magnitudes and spinosaurids showing high stress magnitudes.

When scaled at equalized cranial lengths and forces, small tyrannosauroids and medium-sized tyrannosauroids show relatively high stress that’s either comparable or lower than other similarly-sized theropods. Large deep-snouted tyrannosauroids show relatively lower stress than other large theropods.

For the FEA analyses, we sampled areas of the crania as phylogenetic character data. We also compared the stress magnitudes in both the 2D and 3D models of #tyrannosaurs and found the results to be comparable, supporting 2D FEA’s significance.

For this study we generated 2D models of 50+ theropods and used FEA and phylogenetic analyses to evaluate their feeding function and the evolution of feeding behavior in Theropoda.

There have been numerous analyses investigating the feeding function of an adult #Tyrannosaurus, but there have been few analyses that broadly examined other tyrannosauroids, in addition to other non-tyrannosauroid 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

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
