Granted. However, the Serengeti model ultimately falls short, since there=
is no predator large enough to even consider going after a full grown=
elephant. In the Late Cretaceous, we do have T. rex, who would probably be=
a match for a ceratopsian (if caught off guard). A great deal more work=
will have to be done before we will be able to say what carnivore=
considered Triceratops a part of the menu.
