Triceratops' head was its most imposing feature. It measured 4 to 5 feet (1.2 to 1.5 meters) across and was ornamented with impressive horns and a head plate. It used its horns -- a short one above its mouth and two long ones above its eyes -- to charge predators, such as T. rex. They likely were also used in mating rituals.
