RE: Carnivorous ceratopsids?
Coupled with that is the fact the mechanical possibility doesn't necessarily
equate to behavioural
certainty (or even likelihood).
The beaks of many parrots are more than capable of being used to kill and eat
small animals, yet
the New Zealand Kea is the only parrot that I'm aware of that regularly does
physiology allows them to do headstands when trained to do so in captivity, yet
I doubt any wild
elephant has ever found the need to do so. I'm sure there are plenty of other
examples of species
(or individuals within a species) doing unexpected things that their close
relatives should also be
capable of doing (yet never actually do).
