Life restoration

Carnotaurus, a large theropod dinosaur, lived during the Late Cretaceous period. Known from a single well-preserved skeleton found in Argentina, it is a member of the Abelisauridae family, and one of the best-understood theropods from the Southern Hemisphere. Carnotaurus (derived from Latin for "meat-eating bull") had thick horns above the eyes, and a very deep skull on a muscular neck. It was a lightly built, bipedal predator, 8 to 9 m (26.2 to 29.5 ft) long, weighing at least 1.35 metric tons (1.49 short tons). It had small, vestigial forelimbs and long and slender hindlimbs. Preserved skin impressions show a mosaic of small scales interrupted by large bumps that lined the sides of the animal. The horns and neck may have been used in fighting others of its kind. Its feeding habits remain unclear: some studies suggest the animal was able to hunt down very large prey, while other studies find it preyed mainly on small animals. Carnotaurus may have been one of the fastest large theropods. (Full article...)
