This morning saw the publication of my new paper with Colin Boisvert, Brian Curtice, and Ray Wilhite: Boisvert, Colin, Curtice, Brian, Wedel, Mathew, & Wilhite, Ray. 2024. Description of a new specimen of Haplocanthosaurus from the Dry Mesa Dinosaur Quarry.

Hey guess what? It’s gonna be another really short photo post. Here are some pix of the Jimbo material on display at the Wyoming Dinosaur Center. Many thanks to Tom Moncrieffe of the WDC for taking a good chunk of his day to show me around.

That’s FMNH PR 25107, better known as a the holotype of Brachiosaurus altithorax — the biggest known dinosaur at the time of its description (Riggs 1903) and still for my money one of the most elegant, along with its buddy and one-time genus-mate Giraffatitan brancai . I had a spare morning in Chicago two Tuesday ago, and Bill Simpson (collection manager of fossil vertebrates at the Field Museum) managed to fit it a collections

Long-time readers will recall that I’m fascinated by neurocentral joints, and not merely that they exist (although they are pretty cool), but that in some vertebrae they migrate dorsally or ventrally from their typical position (see this and this). {.size-large .wp-image-20346 .aligncenter loading=“lazy” attachment-id=“20346”
