Centrosaurus is a genus of herbivorous ceratopsian dinosaurs from the late Cretaceous of Canada. Their remains have been found in the Dinosaur Park Formation, dating from 76.5 to 75.5 million years ago. The massive bodies of Centrosaurus were borne by stocky limbs, although at up to 20 ft (6m) they were not particularly large dinosaurs.
