So this little bugger by Favorite Co. is a therizinosaur now!

That's cool, previously it had just been seen as a 'who-knows' generic coelurosaur.

And hey, I recognize that photo!

[austrosaurus]

Between this and Ornitholestes being an oviraptorosaur, it seems like a lot of "generic" late Jurassic-early Cretaceous coelurosaurs will probably end up being basal members of established groups.

Wait what? Where is this Ornitholestes paper?

Wait what? Where is this Ornitholestes paper?

In an abstract presented at the SVP 2021 conference, Chapelle et al. (2021) classify Ornitholestes as the first Jurassic oviraptorosaur from North America based on new data on the cranial morphology of the holotype based on CT scanning of the skull of AMNH 619. The results of the abstract are yet to be published, but when they come out, the classification of Ornitholestes as an oviraptorosaur will illuminate the early evolution of the oviraptorosaur cranial bauplan, notwithstanding the fact that Pittman and Xu (2020) classify scansoriopterygids as basal oviraptorosaurs. As with Coelurus, Tanycolagreus, and Tugulusaurus, the relevance of the SVP abstract by Chapelle et al. to the overall anatomy of Ornitholestes further highlights the fact that early representatives of many non-paravian maniraptoran clades were small, cursorial dinos with sharp teeth.
