I got this thing a while back. I’d always wanted one, and it really does spark joy. First up: what should we call this critter? AFAIK, the species name has never been in doubt, it’s always been [Somegenus] megalodon.

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). A few years ago I learned that there is a term for the expanded bit of […]

Darren, the silent partner at SV-POW!, pointed me to this tweet by Duc de Vinney, displaying a tableau of “A bunch of Boners (people who study bones) Not just paleontologists, some naturalists and cryptozoologists too”, apparently commissioned by @EDGEinthewild: As you can see, Darren, Matt and I (as well as long-time Friend Of SV-POW!

It’s been a while since we checked in on our old friends Elsevier, Springer Nature and Wiley — collectively, the big legacy publishers who still dominate scholarly publishing.

Vertebrae of Haplocanthosaurus (A-C) and a giraffe (D-F) illustrating three ways of orienting a vertebra: articular surfaces vertical — or at least the caudal articular surface vertical (A and D), floor of the neural canal horizontal (B and E), and similarity in articulation (C and F). See the paper for details! Taylor and Wedel (2002: fig.

They grow up so fast, don’t they? Matt and I, with our silent partner Darren, started SV-POW! fifteen years ago to the day, as a sort of jokey riff on NASA’s Astronomy Picture of the Day.

The largest dinosaurs had individual cells more than 30 meters long. How did such things develop? Read on! Illustration from Wedel (2012: fig. 2). Here’s something that’s been in the works for a while: a popular article in Scientific American on stretch growth of axons in large, fast-growing animals: Smith, Douglas H., Rodgers, Jeffrey M., Dollé, Jean-Pierre, and Wedel, Mathew J. 2022.

This is the first 3D print of a dinosaur bone that I ever had access to: the third caudal vertebra of MWC 8028, the ‘new’ Haplocanthosaurus specimen from Snowmass, Colorado (Foster and Wedel 2014, Wedel et al. 2021). I’ve been carrying this thing around since 2018. It’s been an aid to thought.

Years ago, when I was young and stupid, I used to read papers containing phylogenetic analyses and think, “Oh, right, I see now, Euhelopus is not a mamenchisaurid after all, it’s a titanosauriform”. In other words, I believed the result that the computer spat out.

UPDATE: Y’all came through! I’m very happy to announce that Vicki’s scholarship is fully funded, and we’ll be able to give out the first scholarship in the spring of 2023 — and every year thereafter. Thank you, thank you, thank you!!

I am co-authoring a manuscript that, among other things, tries to trace the history of the molds made by the Carnegie Museum in the early 1900s, from which they cast numerous replica skeletons of the Diplodocus carnegii mount (CM 84, CM 94, CM 307 and other contributing specimens). This turns out to be quite a […]
