In a comment on the previous post, Steve P. asked whether “ Apatosaurus ” minimus might not be a Apatosaurus specimen after all — particularly, an Apatosaurus ajax individual resembling NSMT-PV 20375, the one in the National Science Museum, Tokyo, that Upchurch et al. (2005) so lavishly monographed.

Thanks to the wonder of Osborn and Mook (1921), we have already seen multiview illustrations of the pubis and ischium of Camarasaurus . Now we bring you their Camarasaurus sacrum.

More of my thoughts on the Finch Report; you may wish to read part 1 first.

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.

I mentioned a few posts ago that Matt and I are working on a redescription of AMNH 675, a sauropod specimen referred by Mook (1917) to “ Apatosaurus ” minimus , but which everyone knows is not Apatosaurus . We plan to share the illustrations from this in-progress paper as we prepare them, so here is perhaps the key one: {.size-full .wp-image-6480 aria-describedby=“caption-attachment-6480” loading=“lazy”

A couple of posts back, when Matt was talking about turtle laminae, he included a photo of me in front of the skeleton of the giant turtle Archelon . Also in that photo is the tripod I was using — if you want to call it that — a tripod of altogether startling inadequacy.
