This past weekend I was camping up the coast at Hearst San Simeon State Park, with my son, London, and Brian Engh. We went to see the elephant seal colony at Piedras Blancas. It was my first time seeing elephant seals in the wild.

As part of a major spring cleaning operation that we started the first week of January, this week I opened the last two boxes left over from when we moved into our current house. One of them had a bundle of framed art.

There’s a new paper out, describing the Argentinian titanosaur Mendozasaurus in detail (Gonzalez Riga et al. 2018): 46 pages of multi-view photos, tables of measurement, and careful, detailed description and discussion. But here’s what leapt out at me when I skimmed the paper: Just look at that thing. It’s ridiculous.

Here’s OMNH 1330, another vertebra from the big Oklahoma apatosaurine. Based on the size and shape of the transverse process, and the large pneumatic chambers on either side of the neural canal, I think this is probably a 4th caudal, but it could plausibly be a 3rd or a 5th.

In the first installment in this series (link), we looked at a couple of weird sauropod vertebrae with neurocentral joints that were situated either entirely dorsal or ventral to the neural canals. This post has more examples of what I am calling “offset” neurocentral synchondroses.

When I was nine, a copy of Don Glut’s The New Dinosaur Dictionary turned up in my local Waldenbooks. It wasn’t my first dinosaur book, by far – I’d been a dinosaurophile since the age of three. But The New Dinosaur Dictionary was different.

Computer programmer, essayist and venture capitalist Paul Graham writes: In most fields, prototypes have traditionally been made out of different materials. Typefaces to be cut in metal were initially designed with a brush on paper. Statues to be cast in bronze were modelled in wax.

This post started out as a comment on this thread, kicked off by Dale McInnes, in which Mike Habib got into a discussion with Mike Taylor about the max size of sauropods. Stand by for some arm-waving. All the photos of outdoor models were taken at Dino-Park Münchehagen back in late 2008.

Here’s BYU 12866, a mid-cervical of a neosauropod from Dry Mesa Quarry. It’s cataloged as Brachiosaurus, an identification I’ve never found any compelling reason to doubt. It’s definitely brachiosaurid, and for now Brachiosaurus is the only game in town for the Late Jurassic of North America.

Vicki and London and I were in downtown Los Angeles for a friend’s wedding on Dec. 30, and afterward we visited The Last Bookstore. Embarrassingly, even though I’m LA-adjacent, I had not been before.

Hey, look, a new sauropod vertebra to kick off the new year! I’ve blogged a lot about the giant – and tiny – apatosaurines from the Morrison Formation of Oklahoma, and just once on Saurophaganax. But otherwise I don’t think I’ve covered any of the other Oklahoma Morrison dinos.
