Very excited to share my exploration of the phylogenetics of early ray-finned fishes, out today in the Anatomical Record! Really busy day but I’ll have more info shortly.

Tolchard, F. B., Perkins, B. W., & Nesbitt, S. J. 2025 Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms. The Anatomical Record, 1–21. doi.org/10.1002/ar.2...

Check out our new paper (and my first!) on silesaurid material from the Dockum Group of Texas. This material extends the temporal range of silesaurids in southwestern North America and elucidates the high range of individual and ontogenetic variation in early dinosauriforms!

I know this sentiment is well shared, but every once in a while I think about how beautifully powerful and inspiring these paintings are.

This is not a drill, a mummified sabretooth cat has been published from the #Pleistocene permafrost of Russia. It's a Homotherium cub! The team (Lopatin et al.) reckon it's Homotherium latidens. It's too young to have enlarged upper canines. Paper is OA ... www.nature.com/articles/s41... cont...
