NEW PAPER: Our large-scale osteohistological analysis of a population of the Late Triassic theropod dinosaur Coelophysis bauri from the famous Ghost Ranch, New Mexico quarry is now published in @SciReports! Gorgeous new artwork by @ChrisDPiazza. 🧵/20 nature.com/articles/s4159…

#FossilFriday Specimens of the Triassic theropod Coelophysis from Ghost Ranch, NM @NMMNHS_Paleo

🦕 A new species of baby #dinosaur discovered from South Korea's Aphae Island has been named after one of the most beloved cartoon characters in the country: Dooly. Check out our latest blog post to learn all about this exciting discovery: blog.pensoft.net/2026/03/19/fos…

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

New paper from our team, led by @EJR_Paleo_MSc!

Johnson-Ransom, E., Gignac, P., Barta, D. E., Felice, R. N., & Snively, E. (2026). Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea. The Anatomical Record, 1–41. doi.org/10.1002/ar.701…

New research on juvenile Redondasaurus fossils from Chinle Fm. reveals that immature phytosaurs show a mosaic of traits seen in both early and late-diverging species. Links b/w growth & morphological evolution in Phytosauria Goldsmith & Stocker: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar…

@NotThatMarsh @Texaspaleo @Paleo_Tykoski @museumofnaz Exciting!

Proof of life for our #kayentakatae project for @Texaspaleo and @Paleo_Tykoski. Knocked out the braincase description today! @museumofnaz

OSU-CHS Student Abdullah Gohar’s study of 43-million-year-old whale fossils reveals these ancient creatures had large brains and keen smell - before they were fully aquatic. Full story here: bit.ly/4ojDamh #Paleontology #Research

@imai_takuya @PeerJLife Congratulations Takuya! Amazing skull!

It always feels nice to announce a new publication with which I'm so lucky to be involved. Ishikawa et al. (2025) Cranial anatomy of Psittacosaurus houi peerj.com/articles/19547/ @PeerJLife

@RGGSatAMNH @TyrantLzrdQueen Congrats @TyrantLzrdQueen!!

Congratulations to Dr. Amelia Zietlow on a successful Ph.D. dissertation defense (#51, 5/1/2025)!

@TheCassowaryKid @AnatomyOrg @NYITCOMAR Oh no! Hope you’re doing ok, Todd.

While attending the @AnatomyOrg conference, I suffered a medical emergency. I sincerely thank my medical team/staff in Portland, family, friends, & colleagues for their support. This amazing #cassowary card from my @NYITCOMAR department made me feel very welcome upon my return!

Go Erika! I’m looking forward to this, I’ve learned so much from serving on your PhD committee. Almost there!

@gulosuchus Congrats Keegan!!

I am so excited that the last chapter of my dissertation is published. In it, we investigate why crocodylomorphs seem to be so good at making it through mass extinctions but also why their responses to these events appear to differ. onlinelibrary.wiley.com/doi/10.1111/pa…

Congratulations to RGGS Comp Bio PhD alum Eugenia Gold for her tenure promotion to Associate Professor at Suffolk University, Boston!

Many theropods shortened their arms and lost fingers. How did they do it? Our @GeosciencesEd student Milly Mead, in her first paper, looks into oviraptorosaurs. Turns out, arm shortening and finger loss were decoupled! royalsocietypublishing.org/doi/10.1098/rs…

Happy to see that our description of two beautiful specimens of the enigmatic oviraptorid dinosaur, Conchoraptor, was just published in AMNH Novitates: bioone.org/journals/ameri… (We're aware of the formatting issue in some figures, and are working on amending)
