Very excited to share that our latest paper is out in Science! We show that the type specimen of Nanotyrannus—an isolated skull—is fully grown, showing that it is not a juvenile Tyrannosaurus rex but a distinct species (1/12) www.science.org/doi/10.1126/...

Super excited and thrilled to see this work come out in Nature today. 🥹@tdcapellini.bsky.social Thank you so much for your amazing mentorship throughout the project, and to all my co-authors who helped take this work to the next level.

Thrilled to have co-written a News & Views with P. Janvier on Haridy et al.’s recent Nature paper. They reveal that Anatolepis, once thought to have the oldest dental tissue, is actually Cambrian arthropod sensory armor! Paper: nature.com/articles/s41... N&V: www.nature.com/articles/d41...

Fossil data shed light on a debate about when vertebrate dental tissues arose by assigning an early sensory structure to arthropods rather than to vertebrates.

@philipcball.bsky.social gets a bit spicier in places than I did, "it can be hard to avoid the suspicion that sometimes its (omics data) collection serves to postpone the awkward time when some sense must be made of it all." And I like it :)
