If Allosaurus and Acrocanthosaurus teeth were sufficient to kill their
sauropods (albeit perhaps with aid of talon-based wounds), why wouldn't the
even-larger Giganotosaurus teeth be sufficient?
The different sized (and more importantly, shaped!) teeth of tyrannosaurids
most likely represents a different in the style of their feeding, not in the
size of the "target audience." Ditto spinosaurid teeth.
