Carnotaurus sastrei  Bonaparte, 1985

Carnotaurus /ˌkɑrnɵˈtɔrəs/ (Latin carno [carnis] = flesh + taurus = bull); meaning "meat-eating bull", referring to its distinct bull-like horns, a large predatory dinosaur. 
Only one species, Carnotaurus sastrei has been described so far. Carnotaurus lived in Patagonia, Argentina (La Colonia Formation) during the Campanian or Maastrichtian stage of the Late Cretaceous. It was discovered by José Bonaparte, who has uncovered many other South American dinosaurs.

Amargasaurus is fending off a pack of Carnotaurus in the land of Argentina of the early Cretaceous times.
