Now considered a junior synonym of Supersaurus, on very solid grounds.

Incidentally, unlike the neural spines of most non-titanosaurian sauropods, the neural spine of this vertebra is not simply a set of intersecting plates of bone. It is hollow and has a central chamber, presumably pneumatic. Evidence:

    Sweet! I love sauropod vertebrae!

    I seem to recall this particular element was the subject of one of our first substantial discussions — me having swallowed Jensen’s original referral to Brachiosauridae, you explaining why that was mistaken. I hope you got the full set of photos?

    Yeah, they’re great. Someone should do a whole blog just about those things.

    I hope you got the full set of photos?

    Tragically, no. I took this when I was at BYU in 2008 filming a documentary (blogged about here)–I only got a handful of hurried snaps here and there between takes. And of course photogrammetry was not even on my radar back then.

    I am pretty sure that in a decade or so I will look back and divide all of my photos from museum collections into two sets: pre-photogrammetry, and adequate.

    I remember when (as a kid) I first saw the name “Dystylosaurus” I thought it was the best one ever…
