Styracosaurus Dinosaur Frill Spike from Montana

Description: Description: Styracosaurus was a genus of herbivorous ceratopsian dinosaurs from the Cretaceous Period (Campanian stage), about 76.5 to 75.0 million years ago. It had four to six long horns extending from its neck frill, a smaller horn on each of its cheeks, and a single horn protruding from its nose. Styracosaurus was a relatively large dinosaur, reaching lengths of 5.5 meters (18 ft) and weighing nearly 3 tons. Like other ceratopsians, this dinosaur may have been a herd animal, traveling in large groups, as suggested by bonebeds. This specimen is a worn frill spike of this unusual dinosaur.
