Carnotaurus is the only known carnivorous bipedal animal with a pair of horns on the frontal bone. [45] The use of these horns is not entirely clear. Several interpretations have revolved around use in fighting conspecifics or in killing prey, though a use in display for courtship or recognition of members of the same species is possible as well.
Carnotaurus is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern Landmasses of Gondwana during the late Cretaceous. Carnotaurus was a lightly built, bipedal predator, measuring 8 to 9 m (26 to 30 ft) in length and weighing at least 1 metric ton (0.98 long tons; 1.1 short ...

Bipedalism is a form of terrestrial locomotion where an animal moves by means of its two rear (or lower) limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped / ˈ b aɪ p ɛ d /, meaning 'two feet' (from Latin bis 'double' and pes 'foot').

Brachyrostrans were relatively lightly built compared to other large theropods, ranging in size from 6.1–7.8 m (20–26 ft) [3] and 1400–2000 kg (1.6–2.3 short tons) in weight. [ 3 ] [ 4 ] They are considered the most derived abelisaurids, with traits like very short, narrow skulls and extremely reduced forearms, even more so than other ...
