It may very well be that Tany was previously named, so offer your evidence.
Currently there is no evidence - I got nuttin'. There is no reason to
believe that there was not more than one Morrison tyrannosauroid: Tany and
Stokesy. In fact, there may have been several tyrannosauroids scooting
around North America during the Late Jurassic, especially if (a) the
tyrannosaurid/itemirid-like braincase from CLDQ that was (provisionally)
referred to _Stokesosaurus_ represents a new taxon; and/or (b) the
_Stokesosaurus_-like ilium from South Dakota comes from another taxon (maybe
_Aviatyrannis_). I was just reiterating the possibility that
_Tanycolagreus_ and _Stokesosaurus_ *might* be the same (which,
incidentally, would give a very decent skeleton); I was in no way endorsing
Personal opinion (contrary to what Bakker may think) is not scientific
What??!! Now you tell me!!!

Tracy Ford wrapped things up with a review of the tyrannosauroid record
through time. While I don't agree with all his taxonomy or systematics
(i.e., the inclusion of Iliosuchus or Siamotyrannus in Tyrannosauroidea),
he did show that tyrants spent most of their
history as small-bodied critters.
This is interesting, given that there is currently no evidence that the
small-bodied tyrannosauroids survived into the Late Cretaceous (unless
_Itemirus_ is a tyrannosauroid - and even this critter lived much earlier
than the big-ass tyrannosaurids of the Campano-Maastrichtian). Late
Cretaceous dromaeosaurs, by contrast, came in all sizes.
