Dinosaur Carnotaurus was a large bipedal dinosaur which lived in South America during the Late Cretaceous Period. It is a relative of other theropod dinosaurs such as Abelisaurus, Majungasaurus, Ceratosaurus, and Rajasaurus. Carnotaurus lived in Patagonia, Argentina about 80 million years ago.Dinosaur Carnotaurus was a large theropod and one of the largest abelisaurs, about 8–9 meters in length, and between 2-3 tons in weight. Abelisaurids have odd features in their heads, as Carnotaurus had two large brow horns over its eyes, while its smaller relative Majungasaurus had a highly bizarre looking knob on its head. It is probably the fastest running theropod, reaching a speed of up to 40 mph. All these Dinosaur Carnotaurus pictures were collected from the internet. Enjoy!
