This dinosaur belonged to the family of shortfrilled ceratopsians (horned dinosaurs). Others were the tiny Brachyceratops and the much large Monoclonius and Pachyrhinosaurus. These were almost as big as Centrosaurus.

Like Monoclonius, Centrosaurus had a single horn on the top of its nose that curved forward instead of back. It also had a bumpy frill with two pieces of bone shaped like hooks. Centrosaurus had small hooves like a rhinoceros and very thick legs. Each back leg had four stumpy toes and each front foot had five "fingers." Centrosaurus had very strong jaw muscles to help it grind tough food.

Scientists believe Centrosaurus travelled in herds. A single fossils find of eighteen separate animal has been discovered in Alberta. The most famous ceratopsian dinosaur is Triceratops. They lived mostly in great herds and roamed far and wide for root food and plants. In this way they must have been like great herds of bison ambling across the prairie.
