Back in 2012, when Matt and I were at the American Museum of Natural History to work on “ Apatosaurus ” minimus , we also photographed some other sacra for comparative purposes. One of them you’ve already seen — that of the Camarasaurus supremus holotype AMNH 5761.

Today is a good day for sauropod science. Since we’re not getting this up until the afternoon, you’ve probably already seen that Emanuel Tschopp and colleagues have published a monstrous specimen-level phylogenetic analysis of Diplodocidae and, among other things, resurrected Brontosaurus as a valid genus.

We have a new page on the sidebar – here – where we’re collecting as many museum abbreviations as possible, the idea being that you can copy and paste them into your papers to rapidly populate the ‘Museum Abbreviations’ section.

One thing that I’ve never understood is why some people are skeptical about sauropods using their tails defensively, when lizards do this all the time.

Go to Google and do a picture search for “natural history museum”. Here are the results I get.
