The Carnotaurus, classified as Theropoda abelisauridae, were some of the most powerful predators in the prehistoric world. Among carnivorous dinosaurs, the shape and body structure of the Carnotaurus is very unique. This is not only because of the "horns" on its head. Compared to other large theropods, the Carnotaurus has a smaller head, a longer neck, longer leg bones, and a longer chest. The overall shape of its bone structure is very slender.
