Paleontologists from the Royal Tyrell Museum in Canada have discovered what they're calling the largest dinosaur graveyard near the hamlet of Hilda in the province of Alberta.
The bonebed covers nearly a square mile and contains thousands of bones of the ceratopsian dinosaur Centrosaurus apertus, a distant relative of the better-known Triceratops. The discovery is detailed in a new book from Indiana University Press titled, New Perspectives On Horned Dinosaurs.
Scientists involved with the study speculate that flooding caused by hurricanes or tropical storms in the Cretaceous Seaway that divided North America killed entire herds of centrosaurs resulting in the large accumulation of their remains.
