I talked to Phil about this eariler this year and he was very adiment
about the differences. Mainly in the braincases. The Acrocanthosaurus
skull is crushed flat.

Giganotosaurus, Carcharodontosaurus is closer to..., well, I Really
can't say because of the work being done on Giganotosaurus (I don't
want a certian person to get peived at me again). But I side with Phil.
