Last time I promised you exciting news about sauropod neck-muscle mass. Let none say that I do not fulfil covenents. And, as usual, when talking about sauropod neck muscle mass, I’m going to start by talking about bird legs. Look at this flamingo: Ridiculous, right? Those legs are like matchsticks. How can they possibly work. Where are the muscles? And the answer of course is that they’re on this ostrich: Check out those huge drumsticks!

Here are some cervical ribs of sauropods that show a spectrum of morphologies, from a low dorsal process that makes an obtuse angle with the shaft of the rib in Dicraeosaurus (upper right), to one that makes a right angle in Brontosaurus (center), to a prominent spike of bone in Apatosaurus (bottom left), to a […]

A few sauropods have bifurcated cervical ribs. The most dramatic example that I know of is the turiasaur Moabosaurus (Britt et al. 2017). Mike and I got to see that material on the Sauropocalypse back in 2016, which is how we got the photo above.

…that we have somehow managed to not blog about yet. It’s figured by Foster et al. (2018: fig. 18E-F), which is a free download at the link below.

More on this and other apatosaurine vertebrae in the future.

I spent last week bombing around Utah and western Colorado with Dave Hone, who was over from England to visit those states for the first time in his life. We did some fieldwork out at Brachiosaur Gulch and visited quite a few museums and quarries around the Dinosaur Diamond, in a sort of mini-recapitulation of my 2016 Sauropocalypse with Mike.

Some quick backstory: lots of sauropods have long, overlapping cervical ribs, like the ones shown here in Sauroposeidon (diagram from this old post): These long cervical ribs are ossified tendons of ventral neck muscles, presumably longus colli ventralis.
