Powerful Charge (Ex): When a cave triceratops charges, its gore attack deals 4d6+12 points of damage.

Trample (Ex): Reflex DC 18 half. The save DC is Strength-based.

A cave triceratops doesn't fear combat, or much of anything. Unless it's badly wounded, it prefers to trample creatures that disturb it underfoot.
