Cool detailed account by @sobralg.bsky.social on some of the back stage stories behind our paper
Gabriela SobralSo, I will take the opportunity to write about our paper on the new fossil snake 🐍 from Brazil out in @nature.com today. Tiago wrote on the science itself here 👇 so I will tell a bit about the behind the scene stages, especially segmentation and anatomical interpretation bsky.app/profile/trsi...
Proud to share our latest paper in out in Nature today on the origin of #snakes. We present Tametara mirim, an articulated 3D preserved stem snake from the Late Cretaceous of Brazil. Tametara helped us re-tell the story of snake origins in a novel way... www.nature.com/articles/s41...

Almost as a small Christmas miracle, our second (and final) response to the supposed presence of varanoids in the Triassic: doi.org/10.7554/eLif... With M. Caldwell, S. Scarpetta, C. Brownstein, D. Meyer, and M. Lee
Cryptovaranoides is not a squamateClaims for a Triassic-aged crown lizard merit detailed reanalysis, the results of which find that Cryptovaranoides is not only not a lizard, but is a more distantly related diapsid reptile.doi.orgOur lab's PhD student Daniel's take on body size biases in tetrapod taxonomy: nsojournals.onlinelibrary.wiley.com/doi/10.1002/...
Too big to miss: body size biases in tetrapod species descriptions and their implications for conservationWhile species descriptions are rooted in biological diversity, their timing and patterns have also been influenced by historical, socioeconomic, and perceptual biases. Among these, body size has long...nsojournals.onlinelibrary.wiley.comOur big squamate origins and early evolution review is now fully published as open access! with @marcanthonytollis.bsky.social and F.

Origin and Early Evolution of Squamates and Their Kin: From Fossils to GenomesSquamates (lizards, including snakes) are the most diverse group of terrestrial vertebrates on Earth today and have an evolutionary history dating back to at least the Middle Triassic (ca. 242 Mya).
