To clarify for those who are a little surprised by the membership of
the Tyrannosauria given above...
Shanshanosaurines is a term erected (by George) for the basal
Tyrannosauridae, or Aublysodontinae. This is undoubtedly
paraphyletic. It includes _Aublysodon_ (or _Stygivenator_),
_Shanshanosaurus_ and possibly _Alioramus_ (although the braincase
suggests that it might be a very derived tyrannosaurine).
_Aublysodon_, as George has pointed out on many occasions, was named
from teeth that are probably not diagnostic at the genus level.
_Shanshanosaurus_, I've heard, could just be a juvenile _Tarbosaurus_
- the original reconstruction needs a little work.
_Compsognathus_ IMHO never looked like a tyrannosauroid. With the
discovery of _Sinosauropteryx_ and doubt surrounding the
interpretation of the manus of _Compsognathus_ as didactyl, the
Compsognathidae are more likely to be basal coelurosaurians.
_Tonouchisaurus_ - has this thing been described?
_Itemirus_ - braincase shows features in common with both
tyrannosaurids and dromaeosaurids. Still need a body, or more of the
_Stokesosaurus_ - firming as a tyrannosauroid with the referral of an
extraordinarily derived (for a Late Jurassic theropod) and
somewhat tyrannosaurid-like braincase to this genus. The article
appeared in JVP sometime earlier this year.
