This is SUSA 515, a partial skeleton of Camarasaurus on display in the Museum of Moab. (SUSA stands for Southeastern Utah Society of Arts & Sciences.) It was described by John Foster in 2005.
I like this thing. The neural spines are blown off so you can see right down into the big pneumatic cavities in the dorsal vertebrae. And unlike the plastered, painted, and retouched-to-seeming-perfection mounted skeletons in most museums, this specimen reflects how most sauropod specimens look when they come out of the ground. With a few dorsal centra, a roadkilled sacrum, and some surprisingly interesting caudals, it puts me strongly in mind of MWC 8028, the Snowmass Haplocanthosaurus (another John Foster joint: see Foster and Wedel 2014).
Frankly, it doesn’t look like much: 17 centra and some odd bits of pelvis. Surely, with so many good Camarasaurus specimens in the world, this one couldn’t possibly have anything new to tell us about the anatomy of that genus. And yet, it has a couple of unusual features that make it worthy of attention. My colleagues and I are working on those things right now, and you’ll be hearing more about this specimen in the very near future.
