Carnotaurus lived in Patagonia, Argentina during the Maastrichtian stage of the Late Cretaceous, and was discovered by José F. Bonaparte, who has uncovered many other South American dinosaurs.

Carnotaurus was a medium-sized theropod, about 9.0 m (30 ft) in length, 3 m tall at the hips, and weighing about 1,600 kg (1.76 tons). The most distinctive features of Carnotaurus are the two thick horns above the eyes, and the extremely reduced forelimbs with four fingers. It is also characterized by its unusually long neck (compared to other theropods), and its small head with box-shaped jaws. It had a small skull, a thick chest, and a thin tail. The eyes of Carnotaurus faced forward, which is unusual in a dinosaur, and may indicate binocular vision and depth perception.

There is a rather puzzling contrast between Carnotaurus’ deep, robust-looking skull and its shallow, slender lower jaw. So far no-one has worked out what this might imply about its methods of feeding.

A single nearly complete skeleton has been described including impressions of skin along almost the entire right side, that show Carnotaurus lacked feathers, unlike the more advanced coelurosaurian theropods (see also feathered dinosaurs). Instead, the skin is lined with rows of bumps, which become larger toward the spine.

I used a Prehistoric Scenes resin conversion kit Carnotaurus head and arms with a vinyl body to create this custom figure.
