Dinosauria

Triceratops’ heavy skill can tell us a lot about its way of life. Its jaw was built to tackle very tough and fibrous plants. It snipped them off with its narrow, hooked beak and then sliced them up with its sharp, scissor-like teeth. The jaws were powered by huge muscles that extended up into the frill. The frill probably acted as an anchor for the jaw muscles, and also protected the neck. Triceratops used its sharp horns mainly for defense against tyrannosaurs, but it also used them in one-to-one combat. The male Triceratops would lock horns with a member of its own kind and head-wrestle, much as deer, antelope, and sheep do today.
