Centrosaurus was first discovered near the Red Deer River in Alberta. Vast bonebeds of Centrosaurus were found in Dinosaur Provincial Park, also in Alberta. Some of these beds are hundreds of meters long and contain thousands of individuals of all ages and all levels of completion.^[2]

This would be explained if they had died while trying to cross a flooded river. A discovery of thousands of Centrosaurus fossils near the town of Hilda, Alberta, is believed to be the largest bed of dinosaur bones ever discovered. The area is now known as the Hilda mega-bonebed.^[3]

The genus Centrosaurus is now understood to include the fossils which used to be classified as Monoclonius.
