Um, careful, in many present ecosystems the top predator is quite small
compared to the top herbivore. ( E.g., lion/African elephant, tiger/Indian
elephant.) If one were to model a late Cretaceous North American ecosystem
on the present-day Serengeti, then the top predator might well be a
lion-sized theropod that took gnu-sized adult herbivores and an occasional
calf of something larger, while the _T._rex_es sat around eating road kill
and playing tiddley-winks with _Triceratops_ in their spare time.
