  Bah. I'll say. The hand, the snout, the extreme similarity to
*Sinornithoides*, structure of the teeth, etc. etc. Pity no pes with
it. May vindicate my little idea about *Garudamimus* having a reversed
arctomet structure, for both the outgroup to Ornithomimosauria
(Troodontidae) and the outgroup to that group (Bullatosauria, but you
knew that, didn't you? ;) being Tyrannosauroidea) one would say it is
more parsimonious to indicate a reversal than the ornithomimids
attaining an arctomet with extactly the same condition and structre as
their larger and smaller relatives. Right?

  Well, it's about time! I've been waiting for five years! (I'm
relatively young, so this is almost a quarter of my life!)
