No problem.  Even here, in the Tyrannosauridae, I think the situation is more 
complicated.  For example, _Dryptosaurus_ (a late-surviving basal tyrannosaur) 
was fairly large, but its forelimbs were not nearly as reduced as those of 
derived tyrannosaurids.  Among tyrannosaurs, the highly abbreviated forelimbs 
appears to be restricted to the latter clade, which took this trend to the 
extreme.

Cheers

Tim
