I have a new paper out: Wedel, M.J. 2012. A monument of inefficiency: the presumed course of the recurrent laryngeal nerve in sauropod dinosaurs. Acta Palaeontologica Polonica 57(2):251-256.

A month ago, I posted an article containing all the examples known to me of that sadly neglected palaeo-art theme, Sauropods Stomping Theropods: Mark Hallet’s Jobaria squishing Afrovenator , Luis Rey’s Astrodon biting/carrying a raptor, Mark Witton’s Camarasaurus grinding juvenile theropods to dust, and of course Francisco Gascó’s and Emily Willoughby’s Brontomerus pieces, both of them showing Bronto

I wasn’t going to write about this, partly because it’s so darn depressing, but mostly because in the wake of this comment it seemed like the “Amphicoelias brontodiplodocus” paper was being withdrawn, and to quote something Mike said off-list, I was happier about the retraction than I was sad about the implied revisionism.

Well, this is frustrating.  Over on the VRTPALEO mailing list, all the talk at the moment is of the new paper by Henry Galiano and Raimund Albersdörfer (2010), describing their rather comically named new species Amphicoelias brontodiplodocus .  And to be fair, the material they’re describing is sensational, and the photographs in the paper are pretty good.

Suddenly it’s camel season here at SV-POW! In the last post, Mike was having some doubts about how far back camels could get their heads. That got me curious, so here are the results of 45 minutes worth of Google Image Search.

As often happens here, a comment thread got to be more interesting than the original post and ended up deserving a post of its own. In this case, I’m talking about the thread following the recent Mamenchisaurus tail club post, which got into some interesting territory regarding mass estimates for the largest sauropods.

Lovers of fine sauropods will be well aware that, along with the inadequately described Indian titanosaur Bruhathkayosarus , the other of the truly super-giant sauropods is Amphicoelias fragillimus .  Known only from a single neural arch of a dorsal vertebra, which was figured and briefly described by Cope (1878) and almost immediately either lost or destroyed, it’s the classic “one that got away”, the animal that sauropod

Introduction Back when the Xenoposeidon paper came out, we suggested that Xeno could be the first repesentative of a new sauropod “family”, and then discussed at some length: what is a “family” anyway?
