It’s well known that there is good fossil material of the giant azhdarchid pterosaur Quetzalcoatlus out there, but that for various complicated reasons it’s yet to be published. But as part of our ongoing quest for pterosaur epipophyses, I have obtained these photos of a pretty well preserved single cervical, probably C3, which is either Quetzalcoatlus or something pretty darned close.

Many thanks for the various people who chipped in, both in comments on the last post and in this thread on twitter, where I asked a bunch of pterosaur experts for their thoughts on epipophyses in pterosaurs. I now know more than I previously knew about epipophyses outside of Sauropoda — and especially outside Dinosauria. I’ll try to credit everyone who contributed.

Matt’s last post contained a nice overview of the occurrence of epipophyses in sauropodomorphs: that is, bony insertion points for epaxial ligaments and muscles above the postzygapophyseal facets. What we’ve not mentioned so far is that these structures are not limited to sauropods. Back when we were preparing one of the earlier drafts of the paper that eventually became Why sauropods had long necks;

Arriving as an early Christmas present, and coming in just a week before the end of what would otherwise have been a barren 2014, my paper Quantifying the effect of intervertebral cartilage on neutral posture in the necks of sauropod dinosaurs is out!

A friend’s daughter owned a pet corn snake, and a hamster. About a month ago, the former got into the latter’s cage — and in a reversal of the usual course of such events, sustained some nasty injuries. As snakes often do, it struggled to recover, and the wound seems to have necrotised.
