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 
so. Elephant 
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).
