In a comment on the last post, Mike wrote, “perhaps the pneumaticity was intially a size-related feature that merely failed to get unevolved when rebbachisaurs became smaller”. Or maybe pneumaticity got even more extreme as rebbachisaurids got smaller, which apparently happened with saltasaurines

An important paper is out today: Carpenter (2018) names Maraapunisaurus, a new genus to contain the species “Amphicoelias“ fragillimus, on the basis that it’s actually a rebbachisaurid rather than being closely related to the type species Amphicoelias altus. And it’s a compelling idea, as the illustration above shows.

In my recent visit to the LACM herpetology collection, I was interested to note that almost every croc, lizard, and snake vertebra I saw had a pair of neurovascular foramina on either side of the centrum, in “pleurocoel” position. You can see these in the baby Tomistoma tail, above.

A while back — near the start of the year, in fact — Szymon Górnicki interviewed me by email about palaeontology, alternative career paths, open access, palaeoart, PeerJ, scholarly infrastructure, the wonder of blogging, and how to get started learning about palaeo.

This is going to set new records for “almost too late to be worth posting”, but here goes. First up, this Wednesday evening, Oct.

Here’s D10 and the sacrum of Diplodocus AMNH 516 in left lateral and ventral view, from Osborn (1904: fig.

The afternoon of Day 1 at TetZooCon 2018 was split into two parallel streams: downstairs, some talks that I would have loved to see;

Last night, Fiona and I got back from an exhausting but very satisfying weekend spent at TetZooCon 2018, the conference of the famous Tetrapod Zoology blog run by Darren Naish — the sleeping third partner here at SV-POW!. What made this particularly special is that Fiona was one of the speakers this time.

WOW! I knew I was dragging a bit on getting around to this vertebral orientation problem, but I didn’t realize a whole month had passed. Yikes. Thanks to everyone who has commented so far, and thanks to Mike for getting the ball rolling on this. Previous posts in this series are here and here.

Well, that didn’t take long. Earlier today, my subterranean hacker collective released thousands of emails exchanged by Mike Taylor and Brian Engh, which touched on numerous issues of national and global security. Of most interest to SV-POW!

My good friend, frequent collaborator, and fellow adventurer Brian Engh has won the John J. Lanzendorf Paleoart Prize for 2D paleoart (there are also categories for 3D paleoart and scientific illustration). He’s in august company;
