Today is the 3rd slopiversary of us having to temporarily close submissions. The problem of "AI"-generated submissions hasn't gone away and is still a huge waste of our time. House policy remains the same: #noAI stories, translation, art, or anything else.

Yucky! Apparently there is a 2,600 ACRE data center that is proposed near Dinosaur Valley in Glen Rose, TX. I grew up loving that area, and I have numerous fond memories of it.

Please help me tell the powers that be we do NOT want this data center.

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

πŸ§ͺ🏺 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.

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 audienceβ€˜s trust in you and in other sci comm.

On this day that supports inclusive futures for women and girls in science, let's not forget all the women that were sidelined, ignored, or forced out of science because they:
- had children
- prioritised family/caring
- did science differently
- questioned boundaries & norms
- fought the patriarchy

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.

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. 🦎

So we have the starting pieces of an interesting puzzle, and hopefully in the next several years we'll be able to say more about the diversity of animals roaming the Morrison countryside. A huge thanks to LJ for bringing me into this project and all my coauthors for their hard work on this!

All three specimens are from the same site (the Simon Quarry in Wyoming) and the Swiss specimen has most an associated skeleton with it! It is in the process of being moved to a new institution, so once that is finished and the skull CT'ed we should be able to say much more about the animal.

We also talk a little about a skull in Switzerland; it has several differences compared to Camptosaurus. Unfortunately, it has been partially restored and has not yet been CT scanned so the conclusions we could draw are limited.

The reason why is still unclear, but it may be a character that could be informative taxonomically! It may also be that other such PVPs have simply been prepared off, suffered taphonomic damage, or been otherwise unrecognized. An interesting avenue for future work, regardless.

We initially assumed that this prong was unique, but a little more work found similar (but not identical) posterioventral prongs on skulls assigned to Camptosaurus at the Tate Museum, BYU, and a skull formerly housed at Thanksgiving Point. It doesn't appear on most Camptosaurus skulls though.
