Turtles finally have a place in the tree of life: X-ray study of South African fossils was a decider
Palaeontologists have got a clearer picture of where turtles fit in the animal kingdom, thanks to analysis of a southern African fossil.

This woman is a QUEEN. But also, did you know. A lot of Natural History scientific illustrators in the 19th century, were usually partners and wives of famous male academics. Buckland, Lyell, Mantell, Murchinson, Gould etc. Their academic output was carried by their (invisible) wives.

I'm still thinking about something @paleeoguy.bsky.social said at PaleoFest that I hadn't heard articulated quite that way before: A fossil and its matrix are both parts of an ancient ecosystem. Preparing out the fossil means destroying one part to access the other.

I think the most wtf moment of #WAVP was the talk suggesting that Troodon was an obligate herbivore based on eggshell nitrogen and nothing else. The same talk implied that Maiasaura was specializing in eating rotten conifer logs when gravid. Definitely puzzling but now I want that Maiasaura paleoart

🧪🏺 Update - authors have new paper showing how useless gen- #AI is for archaeological illustration. All 400 images were multiply inaccurate (physically, socially, technologically, environmentally), even with improved prompts. JUST USE HUMAN EXPERTS & ARTISTS www.cambridge.org/core/journal...
screengran of figure from paper showing four different generated images of a "day in the life of a Neanderthal". All images contain significant inaccuracies from physical characteristics (extremely primitive) to material culture (glass containers), and the lack of women and children is also obvious.

Using AI makes science communication worse. Period. AI use necessarily reduces accuracy, transparency and authenticity. But sci comm *needs* to be accurate, transparent, and authentic. Otherwise you’re just goofing around, which will destroy your audience‘s trust in you and in other sci comm.

Very excited to share Scyllacerta creanae, a new Permian stem-reptile from South Africa known from an aggregation of several individuals. This specimen provides unprecedented detail regarding the anatomy of the early reptile skull. 🦎 (1/🧵)
Graphic illustrating the reconstruction process for Scyllacerta creanae (SAM-PK-K7710). The holotype aggregation specimen (left) comprises four skulls and at least six nearly complete skeletons preserved in lifelike positions. Using synchrotron micro-CT scans of the skulls, the bones could be segmented, digitally isolating them from the matrix and allowing their full morphology to be studied in detail (top center). Combining information from all four skulls, a reconstructed version could be assembled, depicting the likely life appearance (center, with each bone in a distinct color). This reconstruction can be used to make line drawings for science communication and skeletal reconstructions (bottom center). These reconstructions were the basis for a detailed life restoration of the head of Scyllacerta (bottom right, by @LiterallyMiguel). Despite its incredibly small size (top right, compared to a human hand), the known individuals were likely nearing full maturity.
