Styracosaurus

Styracosaurus was a plant-eating dinosaur that lived during the early Cretaceous Period, 65 million years ago. It was an ancestor of Triceratops, with one large horn on its snout, a small horn above each eye, and a spiked neck frill for protection from predators such as T. rex. Like Triceratops, Styracosaurus used its sharp beak to cut leaves from low-growing foliage, such as cycads, and its powerful jaws to chew the tough leaves. A large bone bed with approximately 100 Styracosaurus fossils indicates that Styracosaurus traveled in herds.
