English: Triceratops horridus is well-known for having three horns on its massive head, the two protruding from above the eyes reaching about a meter in length. The front of the snout bore the single nose horn, and was equipped with a large beak in front of its battery of teeth, used for procecessing vegetation. Triceratops horridus was a robust dinosaur, at about 9 m in length and weighing up to 10 t. The skull was among the largest of any land animal, making up nearly a third of its entire length, at 2.5 m. In addition to the horns, the head also sported a large frill, which was likely used in courtship display, as well as defense against predators.
