Here’s a grab-bag of follow-up stuff related to our new paper on neural canal ridges in dinos (Atterholt et al. 2024, see the previous post and sidebar page). Neural canal ridges, or bony spinal cord supports?

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.

This is one of those things I’ve always done, that I’ve never thought to ask if others did. When you’re putting together a talk, or making a complicated figure, do you storyboard it first with a pen or pencil? I usually do, and have done since I started way back when.

I was on a video call with Matt, talking about a project he’s working on that involves Haplocanthosaurus . A lot of his recent project involve Haplocanthosaurus which is … an OK sauropod. I mean, it’s no brachiosaur. So this is how the conversation went: Mike: I have bad news for you, dude. Haplocanthosaurus is only one or two nodes away from being a camarasaur.

In mammals — certainly the most-studied vertebrates — regional differentiation of the vertebral column is distinct and easy to spot. But things aren’t so simple with sauropods.

New paper out today: Wedel, Mathew; Atterholt, Jessie; Dooley, Jr., Alton C.; Farooq, Saad; Macalino, Jeff; Nalley, Thierra K.; Wisser, Gary; and Yasmer, John. 2021. Expanded neural canals in the caudal vertebrae of a specimen of Haplocanthosaurus. Academia Letters, Article 911, 10pp. DOI: 10.20935/AL911 (link) The paper is new, but the findings aren’t, particularly.

Regular readers will remember that we followed up our 1VPC talk about what it means for a vertebra to be horizontal by writing it up as a paper, and doing it in the open.
