This is one of those things that has been sitting in my brain, gradually heating up and getting denser, until it achieved criticality, melted down my spinal cord, and rocketed out my fingers and through the keyboard. Stand by for caffeine-fueled testifyin’ mode.

I have a new paper out in Acta Paleontologica Polonica, with Guillermo Windholz, Juan Porfiri, Domenica Dos Santos, and Flavio Bellardini, on the first CT scan of a pneumatic caudal vertebra of a rebbachisaurid: Windholz, G.J., Porfiri, J.D., Dos Santos, D., Bellardini, F., and Wedel, M.J. 2024.

New paper out today: Tito Aureliano, Aline M. Ghilardi, Rodrigo T. Müller, Leonardo Kerber, Marcelo A. Fernandes, Fresia Ricardi-Branco, Mathew J. Wedel. 2023. The origin of an invasive air sac system in sauropodomorph dinosaurs.

Here’s a nice early holiday present for me: 51 weeks after our first paper together, I’m on another one with Tito Aureliano and colleagues: Aureliano, T., Ghilardi, A.M., Müller, R.T., Kerber, L., Pretto, F.A., Fernandes, M.A.,Ricardi-Branco, F., and Wedel, M.J. 2022.

Here’s figure 1 from my 2005 book chapter. I tried to cram as much pneumatic sauropod vertebra morphology into one figure as I could.

Long before Matt and others were CT-scanning sauropod vertebrae to understand their internal structure, Werner Janensch was doing it the old-fashioned way.

The more I look at the problem of how flexible sauropod necks were, the more I think we’re going to struggle to ever know their range of motion It’s just too dependent on soft tissue that doesn’t fossilise.

I was lucky enough to have Phil Mannion as one of the peer-reviewers for my recent paper (Taylor 2018) showing that Xenoposeidon is a rebbachisaurid. During that process, we got into a collegial disagreement about one of the autapomorphies that I proposed in the revised diagnosis: “Neural arch slopes anteriorly 30°–35° relative to the vertical”. (This same character was also in the original Xenoposeidon
