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.

We’ve shown a lot of sauropod sacra around here lately (for example here, here, and here), so here’s a little look back down the tree. You haven’t heard from me much lately because I’ve been busy teaching anatomy. Still, I get to help people dissect for a living, so I can’t complain.

In the recent post on serial variation in sauropod cervicals, I wrote: Even in ‘adult’ sauropods like the big mounted Apatosaurus and Diplodocus skeletons, the anterior cervicals are less complex than the posterior ones.

Item 1 : With his new piece at the Guardian,  “Persistent myths about open access scientific publishing”, Mike continues to be a thorn in the side of exploitative commercial publishers, who just can’t seem to keep their facts straight.

UPDATE April 16, 2012: The paper is officially published now. I’ve updated the citation and link below accordingly. More new goodies: Yates, A.M., Wedel, M.J., and Bonnan, M.F. 2012. The early evolution of postcranial skeletal pneumaticity in sauropodomorph dinosaurs. Acta Palaeontologica Polonica 57(1):85-100. doi: http://dx.doi.org/10.4202/app.2010.0075 This is only kinda sorta published.

Why we do mass estimates Mass estimates are a big deal in paleobiology.

In case you haven’t heard, Taylor et al . (2009) recently argued that sauropods naturally held their cervico-dorsal junctions in extension, and their cranio-cervical joints in flexion… at least, when they weren’t foraging, feeding or engaged in other such activities [if you need help with those terms please see the Tet Zoo article here].
