  Triceratops was no gentle, plant-eating giant. Many fossil records show damage to Triceratops bones which could have occurred in combat with other Triceratops or predators. The horns of a Triceratops could be used as weapons, as displays of domination to other Triceratops, or as mating displays. The neck frill would have offered some protection against the bite of the Tyrannosaurus rex and perhaps would have regulated body temperature.
