Eoneophron, Parapropalaehoplophorus, Ia io, and friends The other day Mike wrote to me about the new Hell Creek oviraptorosaur Eoneophron (Atkins-Weltman et al. 2024), commenting that he liked the ‘eoneo’ — old new — part of the name. That sent me down a little etymological rabbit hole.

Just a quick post about the genesis of the Brachiosaurus rib paper (Taylor and Wedel 2023) that I wrote about at the very end of last year. Although this is in some respects a minor paper, I’m fond of it because it fell into place so quickly and easily. Taylor and Wedel 2023:Figure.

Everybody(*) knows that the turiasaurian sauropod Moabosaurus has bifurcated cervical ribs: it was all anyone was talking about back when that animal was described (Britt et al. 2017). We’ve featured the best rib here before, and here it is again: (*) All right, but you know what I mean.

I haven’t blogged about blogging in a while. Maybe because blogging already feels distinctly old-fashioned in the broader culture.
