Carnotaurus (kahrn-oh-TAWR-us) meaning "meat-eating bull", referring to its distinct bull-like horns (Latin carn = flesh + taurus = bull) was a large predatory dinosaur, similar to a Tyrannosaurus rex with a head distantly resembling a bull's.
Species: C. sastrei
Carnotaurus lived in Patagonia, Argentina about seventy million years ago, and was discovered by José F. Bonaparte, who has discovered many other bizarre South American dinosaurs.
The most distinctive features of Carnotaurus are the two thick horns above the eyes, and the extremely reduced forelimbs with four fingers. It had a small skull, a thick chest, and a thin tail. The eyes of the Carnotaurus faced forward, which is unusual in a dinosaur, and may indicate binocular vision and depth perception.
A single nearly complete skeleton has been described including impressions of skin along almost the entire right side, that show Carnotaurus lacked feathers, unlike many other theropods discovered recently (see also feathered dinosaurs). Instead, the skin is lined with rows of bumps, that become larger toward the spine.
Carnotaurus was a medium-sized theropod, about 7.5 m (25 ft) in length, 2.2 m (7 ft 3 in) tall at the hips, and weighing about 1,000 kg (1.1 tons).
The type species Carnotaurus sastrei is the only known species. Its closest relatives include Aucasaurus (Argentina), Majungatholus (Madagascar), and Rajasaurus (India). Together, these dinosaurs form the subfamily Carnotaurinae in the family Abelisauridae.
In Popular Culture
Carnotaurus appeared in the novel The Lost World by Michael Crichton (1995) as a colour-changing chameleon-like dinosaur, but this ability is purely speculative. It also appeared in a level of the video game adaptation of the film.

Carnotaurus was set to make an appearance in the movie Jurassic Park III as the dinosaur approaching the characters as they search for a cellular phone within giant heaps of Spinosaurus dung. However this was changed to a Ceratosaurus.
The film Dinosaur features two Carnotaurus as the main antagonists, attacking a large herd of herbivorous dinosaurs. However, the 'lead' Carnotaurus was much larger than the real life animal, supersized to T-Rex proportions, when in real life Carnotaurus was even smaller than Iguanodon, the main dinosaur of the Disney Picture
