Another recent paper (part 1 is here) with big implications for my line of work: D’Emic and Foreman (2012), “The beginning of the sauropod dinosaur hiatus in North America: insights from the Lower Cretaceous Cloverly Formation of Wyoming.” In it, the authors sink Paluxysaurus into Sauroposeidon and refer a bunch of Cloverly material to Sauroposeidon […]

It’s been a looong time coming, but I just got this email from  Ellinor Michel, Executive Secretary of the International Commission on Zoological Nomenclature: Fantastic news.

Gah, so much interesting stuff going on and I simply have No. Time. To. Blog. But I’m making an exception for PeerJ, a new OA journal that is coming online later this year.

No time for anything new, so here’s a post built from parts of other, older posts. The fourth sacral centrum of Haplocanthosaurus CM 879, in left and right lateral view. This is part of the original color version of Wedel (2009: figure 8), from this page. (Yes, I know I need to get around to posting the full-color versions of those figures.

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.

Let me begin with a digression. (Hey, we may as well start as we mean to go on.) Citations in scientific writing are used for two very different reasons, but because the two cases have the same form we often confuse them.

Last time I argued that traditional pre-publication peer-review isn’t necessarily worth the heavy burden it imposes. I guess no-one who’s been involved in the review process — as an author, editor or reviewer — will deny that it imposes significant costs, both in the time of all the participants, and in the delay in getting new work to press. Where I expected more pushback was in the claim that the benefits are not great.

[Note: this post is by Mike. Matt hasn’t seen it, may not agree with it, and would probably have advised me not to post it if I’d asked him.] The magic is going out of my love-affair with peer-review.

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.
