Sauropodan flotsam

This is very nearly the last photo I have from the Carnegie, such a shame, I’ll just have to go again. As noted before the museum does a nice line in small cabinets and displays of elements alongside and this little collection sits below the wonderfully mounted Diplodocus. I assume all of the material here represents that genus but I may have kinda forgotten to take a photo of the label so I don’t know for sure, though the skull at least is a bit of a give away.

Diplodocus skulls again

I did feature one of these a while back – though one that was bolted onto a Mamenchisaurus skeleton. Here we have a cast from the same collections in Ireland as yesterday’s Stegosaurus cranium. This has the mandible separate from the skull, but I’ve put in back on for some shots to show off how they fit together. Diplodocus has a rather iconic skull shape when seen side on, but actually the dorsal view is the one I always find most interesting. It’s so regular with very square sides and just a slight curve to the very front. It seems almost too geometric to be quite natural.

Guest post: Grazing giants – sauropod feeding

In today’s guest post, John Whitlock takes us through his recent PLoS One paper on the wear facets of sauropod teeth and what this might mean for their feeding habits. I’ve long had a general curiosity about this and was delighted to see renewed interest in this area, not least from someone who takes their sci-comms seriously enough to have signed up for AAB! Take it away please John:

Guest Post: Tracking the hand prints of sauropods

Today Peter Falkingham, fresh from finishing his PhD (congratualtions by the way), tells us about his work on dinosaur footprints. Some prints are rather enigmatic and Peter has been working on how they might have formed:

Diplodocus skull

This time out, it’s a rather nice cast of a Diplodocus skull at the IVPP. However, it’s mounted on the end of a Mamenchisaurus skeleton which rather reduced the impact.

Still, that’s not as bad as it sounds, for a very long time there was confusion and disagreement about what sort of sauropods were and although there were quite a few specimens known, no Mamenchisaurus had been recovered with anything like a decent skull. Thus not only did we not know what kind of skull they had, it was hard to guess what kind of skull they might have had since their immediate relatives were not known. As a result, you can see a Diplodocus, Shunosaurus or even Apatosaurus skull attached onto a Mamenchisaurus skeleton in various Chinese museums. Since they don’t always have the money to replace them, these things tend to hang around (and replacing a skull on the end of a 10+ m neck is no mean feat either) it’s perhaps no surprise, though can look a bit odd to those who know better.

Those who aren’t in the know will be pleased to find out that in 2002 a very complete and well preserved Mamenchisaurus was described complete with an intact skull. This looks, superficially at least, like those of brachiosaurs with a nice big internarial bar that arches off the top of the skull.
