IIRC, the distribution of the predatory dinosaurs in the late Cretaceous, as
described by Archibauld in his book on KT-extinction event, was from
Velociraptor (~50 kg) through Dromeosaurus (~100 kg), Abelisaurus (~450
kg), Albertosaur (~2 ton) to T.rex (>4 t). So there was a good distribution of
the predators occupying each size group.
