Chet Gottfried got in touch after he read Yet more lying necks: Backwards Birds edition, nearly two months ago now, with some more of his photos. Here they are, with his permission: What’s going on here? As I wrote the Chet, “Interesting that this degree of twisting is common in raptors.

The dawn of a new era: AMNH FR 34089, a caudal vertebra of the giant extinct croc Thecachampsa , backlit to show the neural canal ridges. This is not just my favorite specimen with NCRs, it’s one of my favorite images of any fossil ever. Photo by William Jude Hart. New paper out: Hart, W.J., Atterholt, J., and Wedel, M.J. 2025. First occurrences of neural canal ridges in Crocodylia. Acta Palaeontologica Polonica 70(4): 749–753.

We’ve written plenty about the problems with what is now ubiquitously called “artificial intelligence”: see for example These new “artificial intelligence” programs don’t know what they’re talking about, Another day, another catastrophic “AI” failure, If you believe in “Artificial Intelligence”, take five minutes to ask it about stuff you know well, What LLMs are really […]

This book is squarely at the intersection of being an objectively great thing to have in the world, and a subjectively great thing to have on my gaming shelf. I’ve been playing tabletop RPGs since I was 16, and running Dungeons &

This one starts with a personal note. I’ve never blogged much about the media whirlwind that accompanied the announcement of Sauroposeidon. Rich Cifelli and I did tons of interviews, separately and together, for local and national television news, newspapers, and magazines.
