Styracosaurus was a four-legged plant-eating dinosaur that had many horns on its head. Styracosaurus lived in herds during the late Cretaceous period, about 77-70 million years ago.
Anatomy: Styracosaurus had a huge skull with a very large, bony, scalloped, head frill. It had a beak, a long snout horn, two smaller brow horns, and many horns protruding from its frill. Styracosaurus was about 18 feet (5.5 m) long, 6 feet (1.8 m) tall, and weighed up to 3 tons.
Diet: Styracosaurus was an herbivore (a plant eater) that ate low-lying plants.
Fossils: Styracosaurus was discovered by paleontologist Lawrence M. Lambe in 1913. Fossilized Styracosaurus skulls have been found in Alberta, Canada, and Arizona, USA.
