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.

I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA

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.

The mummy of an ankylosaurid dinosaur, Scolosaurus, described by the queer Hungarian icon, Franz Nopcsa, in 1928. The holotype with amazingly preserved "carpace" of osteoderms, scutes and skin impressions is on display at the Natural History Museum London. 🪖

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...

(My first post) A hadrosaur arm bone absolutely covered in toothmarks made by a carnivorous #dinosaur, probably a #tyrannosaur, although there have been suggestions that these small marks might be from #raptors. US public lands (BLM); Judith River Fm, Montana; ~76Ma, Cretaceous. #fossilfriday

Seeing nice uptick in followers here as more people migrate over from Twitter. Hi - welcome to BSky! I'm Darren and I write about amphibians, reptiles, birds and mammals (living and extinct); I blog regularly at Tetrapod Zoology tetzoo.com and I also publish #books and academic research...
