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.
