Found in Alberta, Canada, Styracosaurus was a short-frilled ceratopsian with 6 long spikes along the edge of its frill. Its snout was shaped like a parrot's beak. And on its snout grew a horn that was nearly 2 feet (0.6 meters) long and 6 inches (15 cm thick). Possibly it used this great horn for self-defense.
