Centrosaurus was a very large horned dinosaur that lived around 67 million years ago in North America.
Fossil evidence suggests that Centrosaurus moved in large herds from place to place in search of food and water.
Centrosaurus had a large horn near the end of its snout just above its beak-like mouth. Its skull was thicker above its eyes, and it had horns along its neck frill.
Many fossils have been found of Centrosaurus, including a skin impression. This skin impression shows that Centrosaurus had scaly skin.
