I haven’t blogged about blogging in a while. Maybe because blogging already feels distinctly old-fashioned in the broader culture. A lot of the active discussion migrated away a long time ago, to Facebook and Twitter, and then to other social media outlets as each one in turn goes over the enshittification event horizon.

New paper out today in PeerJ: Lei R, Tschopp E, Hendrickx C, Wedel MJ, Norell M, Hone DWE. 2023. Bite and tooth marks on sauropod dinosaurs from the Morrison Formation. PeerJ 11:e16327 http://doi.org/10.7717/peerj.16327 This one had a long gestation.

More goodness from Osborn and Mook’s (1921) gargantuan Camarasaurus monograph, again prepared largely for comparison with “Apatosaurus” minimus. Last time, I showed you one of O&M’s pubis illustrations. Now an ischium: This shows the left ischium AMNH 576o’/Is.4. Left column: proximal aspect.

Here is another illustration that I prepared for the forthcoming “Apatosaurus” minimus redescription. Compare this with the sacrum and fused ilia from the previous post. Can you tell what it is yet? By the way, I’d appreciate some advice on the directional nomenclature here.
