Here at SV-POW!, we love bifurcated cervical ribs. Those of Turiasaurus are one of the autapomorphies proposed by Royo-Torres et al. (2006:figure 1K). Their diagnosis of the new genus included “accessory process projecting caudodorsally from the dorsal margin of the shafts of proximal cervical ribs”. Here is the best example of such a rib in Turiasaurus , attached to its vertebra.

Eighteen months ago, I noted that the Carnegie Museum’s Diplodocus mount has no atlantal ribs (i.e. ribs of the first cervical vertebra, the atlas). But that the Paris cast has long atlantal ribs — so long the extend past the posterior end of the axis. There were two especially provocative comments to that post. First, Konstantin linked to a photo of the Russian cast (first mounted in St. Petersburg but currently residing in Moscow).

New paper out today with Logan King, Julia McHugh, and Brian Curtice, on pneumatic ribs in Apatosaurus and Brontosaurus (King et al. 2024). This one had an unusual gestation. In the summer of 2002 2022 I did a road trip to Utah and western Colorado with my friend and frequent collaborator Jessie Atterholt.
