Darren Naish announced 2 days ago the publication of a new description of Eotyrannus lengi (with Andrea Cau as a coauthor) he's been working on for a very long time.

A summary/thoughts post by Darren Naish on his blog.

Here's the paper.

And here's the new skeletal:

The phylogenetic analysis featured in the paper sheds some interesting results...

- There's no such thing as Stokesosauridae (in which Eotyrannus was nested before).

- Yutyrannus outside of Proceratosauridae.

- Chilantaisaurus is recovered as a Tyrannosauroidea.

- Megaraptoridae were already suspected to be coelurosaurs (and tyrannosauroids) before and this new paper reaffirms it.

- Teratophoneus outside of Tyrannosauridae! (and Bistahieversor too, although IIRC this was already known)

A quick read at his blog entry and I learnt this species' description was preliminary, as suggested by its title: Hutt, S., Naish, D., Martill, D.M., Barker, M.J., and Newbery, P. (2001). "A preliminary account of a new tyrannosauroid theropod from the Wessex Formation (Cretaceous) of southern England." Cretaceous Research, 22: 227–242.

PS 1. Looks like these news have been overshadowed by the announcement of the new carcharodontosaurid Meraxes.

PS 2. Honestly I didn't find Eotyrannus too interesting before, but it's growing on me! Those are unusual proportions for a tyrannosauroid.
