I have a new preprint up at PeerJ (Taylor 2015), and have also submitted it simultaneously for peer review.

Preprints are in the air! A few weeks ago, Stephen Curry had a piece about them in the Guardian (Peer review, preprints and the speed of science) and pterosaur palaeontologist Liz Martin published Preprints in science on her blog Musings of Clumsy Palaeontologist . The latter in particular has spawned a prolific and fascinating comment stream.

Folks, For a forthcoming minor paper, I need a good-quality scan of Hatcher’s 1901 monograph on Diplodocus carnegii — specifically, plate VI, the photographs of the cervicals in posterior view.

We’re delighted to host this guest-blog on behalf of Richard Butler, Senior Research Fellow at the University of Birmingham, and guru of basal ornithischians. (Note that Matt and I don’t necessarily endorse or agree with everything Richard says; but we’re pleased to provide a forum for discussion.) Dear friends and colleagues within the SVPCA community; I am posting here courtesy of Mike and Matt with two objectives.

Here’s the last post (at least for now) in the Fighting Apatosaur Art series — and we’re back to Brian Engh, who we started with. Early in the process of putting together artwork to illustrate our apatosaur neck combat hypothesis, Brian tried out a whole bunch of outlandish concepts. Here are two that he showed us, but which were too speculative to push forward with.

If we accept that the distinctive ventral projections of the gigantic and ventrally displaced cervical ribs of apatosaurs were likely the base of some form of soft-tissue rugosity — such as keratinous horns like those of rhinos — then does it follow that those necks were used in combat as we suggested? Maybe, maybe not. As scientists, we are always open to other hypotheses.

I mentioned last time that, as I sat next to Bob Nicholls in an SVPCA session, I started sketching an apatosaur combat in the hope that my horrible drawing would provoke Bob to do a good one. That worked admirably, which means there is no good reason for me to subject you to my own sketch.

On the morning of Tuesday 1st December, on SVPCA day 1, I gave my talk about apatosaur neck combat. In one of the afternoon sessions, I sat next to Bob Nicholls, and found myself thinking how awesome it would be if he sketched some apato-combat.

Here’s my newest specimen: a tiny baby bird, maybe 5 or 6 cm from wingtip to foot.

The process of reassembling my cat skull continues. I now have the sphenoid and both nasals now back in place, and the time has come for the now-traditional multiview. (Previous examples: pig skull, wallaby skull, sheep skull.

Last time, we looked at some of Brian Engh’s preliminary sketches of pieces to illustrate our fighting-apatosaur hypothesis.
