| phylum | Chordata | Achelousaurus is a genus of centrosaurine ceratopsids from the Late Cretaceous Period of what is now North America, dated to 74.2 million years ago. They were quadrupedal herbivores with parrot-like beaks, rough bosses (raised bony areas) on their snouts and one pair behind their eyes, and a pair of horns on the end of their long bony frills. With body lengths of up to six meters (20 feet) and a weight of three tonnes, Achelousaurus were medium-sized ceratopsians. For more information, visit the Wikipedia entry. Get back to Ceratopsia |
