New paper out today: Xenoposeidon is indeed the oldest rebbachisaur

July 6, 2018

I’m delighted to announce the publication today of my new paperXenoposeidon is the earliest known rebbachisaurid sauropod dinosaur”. This is the peer-reviewed version, in my favourite journal PeerJ, of the manuscript that became available as a preprint eight months ago — which was in turn a formalisation of a blog-post from 2015.

Taylor (2018: Figure 3). Autapomorphies of Xenoposeidon proneneukos NHMUK PV R2095, mid-posterior dorsal vertebra, highlighted in red. A. anterior view. B. left lateral view. Numbers pertain to the numbering of autapomorphies in the text. 1a, neural arch covers whole of centrum, and 1b is contiguous with posterior articular facet. 2, neural arch is inclined forward by 30–35 degrees relative to the vertical. 3a, inclined ridge-like lamina marks ventral margin of 3b broad featureless area of bone. 4, large teardrop-shaped anterior fossa. 5a, vaulted laminae bound this fossa, but are not the medial CPRLs (5b, drawn in finer lines), which continue up to the presumed location of the prezygapophyses.

In a sense, then, this paper is old news. It doesn’t contain any startling new insights that readers of this blog wouldn’t already have been aware of. But it’s become more rigorous, better argued and justified, better illustrated (the image above is one of two new figures), and generally toughened in the forge of peer-review. It’s also now, of course, officially part of the scientific record.

I’m delighted about this paper for several reasons. First, of course, because Xenoposeidon is a beautiful specimen and now turns out to be rather more important than I’d previously realised. Second, because I hope this paper’s inclusion of the high-resolution full-colour 3D model as a supplementary file will help to establish this as common practice. But also third, because it’s my first paper in ages.

In fact, if you were being harsh, you could say it’s my first real paper since the annus mirabilis of 2013 when Matt and I had four good, solid papers come out in a single year. My CV lists five papers between then and now, but a case can be made that none of them really count:

  • Taylor 2014 is essentially an addendum to my and Matt’s PLOS ONE paper the year before.
  • Upchurch et al. 2105 is a significant and substantial piece of work, but almost all the credit on that one is due to Paul and Phil.
  • Taylor 2016 is more of an advocacy piece than a scholarly paper.
  • Ansolabehere et al. 2016 is merely a report summarising a multi-day discussion, and I am in any case only one of nine(!) co-authors.
  • Taylor 2017 is just a short comment on someone else’s ICZN petition. (In fact that one is so feeble I should just remove it from my CV.)

Putting it all together, it’s been the best part of five years since I made a significant contribution to the scientific record, and to be honest I was starting to wonder whether I could still do it. (My deep thanks go to Paul Upchurch and Phil Mannion for keeping my publication record on life-support with that Haestasaurus paper!)

The challenge for me now is, having got back on the horse, to ride it hard. In particular:

That’s not even mentioning other long-in-the-works projects like the descriptions of Apatosaurusminimus and “Biconcavoposeidon”. Sheesh. I’m so lazy. Nearly as bad as Darren.

    Wait, you got the reviews back in 2015-2016? Most of the juournals I send things to will reject the paper if the response isn’t back within 1-5 months unless you provide them with extenuating circumstances (e.g., the reviewers demand you provide photos of a specimen in a far-off institution you weren’t planning on visiting).

  2. Mike Taylor Says:

    Yep, I don’t really know why, but both submissions are still open. So my plan is to make the required changes and resubmit: the worst case is that they treat it as a new submission, after all.
