re: Big theropod olympics

Larry-

Giggy is bigger then rex, and by some estimates may be heavier, too. The "T.
rex is stronger" thing may come from muscle mass estimates, which I haven't
seen yet, if any are out there. The overall look of Giggy is that it is a
more gracile animal than rex (but not compared to most other theropods). Rex
also has that impressive heavy skull- while Giggy's huge skull is massive 
it is not built on the same force-producing model. 

As far as teeth go, rex still has those impressive banana shaped chompers
while Giggy has very thin blade like teeth, like Cararadontosaurus'.
