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.

Introduction and Background I have three goals with this post: To document the range of variation in epipophyses in the cervical vertebrae of sauropods. To show that the “finger-like processes” overhanging the cervical postzygapophyses in the newly described Qijianglong are not novel or mysterious structures, just very well developed epipophyses.
