Fw: Evolution of tyrannosauroid bite power
I'm sorry; I should have written "tyrannosaurids" instead of
"theropods". "Theropods" does cast the net a little wide ... my mistake.

No, this doesn't happen. It's horses for courses. True, tyrannosaurs,
abelisaurs and _Giganotosaurus_ exemplify this trend; but there are
also some quite large theropods that have relatively long arms, such
_Deinocheirus_ and some of the larger maniraptorans (e.g.,
_Gigantoraptor_, large dromaeosaurs, large therizinosaurs).
Don't get caught with egg on your face. Play Chicktionary!
