On 22nd December 2020, I gave this talk (via Zoom) to Martin Sander’s palaeontology research group at the University of Bonn, Germany. And now I am giving it to you , dear reader, the greatest Christmas present anyone could ever wish for: It’s based on a 2013 paper written with Matt Wedel, which itself goes back through many years slow gestation, originating in a discussion on a car journey in 2008.

These things just catch my eye, I can’t help it. Note that the corkscrew features a distinct medially directed femoral head, the bulge in the lateral margin of the proximal portion that is characteristic of titanosaurs, and a straight shaft.

Darren has written a brief review of TetZooMCon, the online event that replaced the now traditional annual conference of Tetrapod Zoology.

I’m late to this party, but I want to say a few things about the recently announced €9,500 article-processing charge (APC) that Nature has introduced to make itself Plan-S compliant. The first thing is that a lot of people are quite understandably outraged by this very large fee.

It’s now 22 years since Tim Berners-Lee, inventor of the World Wide Web, wrote the classic document Cool URIs don’t change [1]. It’s core message is simple, and the title summarises it.

We’re currently in open access week, and one of the things I’ve noticed has been a rash of tweets of the form “I support #OpenAccess because …”. Here is a random collection. We support #OpenAccess because #OpenScience needs good infrastructures. — @ZB_MED We support #OpenAccess because we believe that research results made possible by public funds should be accessible to everyone.

As has been discussed here before, the recurrent laryngeal nerve (RLN) does not only innervate the larynx, but also parts of the esophagus and trachea (see this post, and in particular this comment). You can see that in this cadaver photo, in which the RLN is sending nice big visible branches into both the esophagus […]
