Its mass is proportional to x cubed, it stands on leg bones whose cross-sectional area is x squared, and it ingests food through a gullet whose cross-sectional area is x squared.

I’m currently working on a paper about the AMNH’s rearing Barosaurus mount. (That’s just one of the multiple reasons I am currently obsessed by Barosaurus .) It’s a fascinating process: more of a history project than a scientific one. It’s throwing up all sorts of things. Here’s one. In 1992, the year after the mount went up, S. O.

It’s now on YouTube, on the No Man’s Land Museum’s channel. There’s a point I want to make here, that I also made in the talk: we can’t predict the value of natural history collections.

For reasons that would be otiose, at this moment, to rehearse, I recently found myself in need of a hemisected turkey cervical. Happily, I own five skeletonised turkey necks, so it was with me the work of a moment to select a candidate. But now what? How to hemisect it? We have
