Here is one of the dorsal plates and dorsal vertebrae of the stegosaur formerly known as Wuerhosaurus. This was formally synonymised with Stegosaurus by Susie Maidment back in 2008 but this has barely got a mention in most places and it still goes under its old name most places on the web.
It is with only occasional shame that I remember just how rarely the ornithischians get a stint on the Musings (though they generally fare better than crocs to be honest) so here’s just a smidge on the stegosaurs with a few posts to follow on some of the other ornithiscian specimens at the IVPP. Stegosaurian dorsal vertebrae are easily recognised by their elongate neural arch (that’s the bit between the rounded centrum at the various zygopophyses and neural spine at the top). In this example it’s exceptionally clear as the whole things looks stretched out.
Also included is the truncated dorsal plate which is generally used to illustrate the animal with a characteristic profile. However, the surviving plate really looks broken rather than having a natural termination and thus the true extent and shape of the plate cannot really be determined. It’s a shame really as I really like that short-strips of plates look, but it’s very probably incorrect, though of course we won’t have a good idea of the true shape without a more complete specimen.
