Carnotaurus (Carnotaurus sastrei) was a large predatory dinosaur from the Cretaceous of Patagonia, Argentina. It is one of the most recognizable theropods thanks to its short, deep skull and the pair of thick horns above its eyes.
Time Period
Carnotaurus lived during the Late Cretaceous. In your site’s simplified filter, this is grouped under Cretaceous.
Habitat
Fossils of Carnotaurus come from Patagonia in South America. The environment is commonly reconstructed as a mix of open plains and river-influenced landscapes where fast-moving predators could hunt and patrol large territories.
Size and Appearance
Carnotaurus reached roughly 7.5–9 meters in length. Its skull was short and deep, built for strong bites and rapid head movements. The two horns above the eyes likely played a role in display, recognition, or even physical contests. One of the most remarkable discoveries is its preserved skin impressions, revealing a scaly surface with distinct bumps.
Diet and Hunting Style
As a carnivore, Carnotaurus preyed on other animals. Its arms were extremely small, so it probably relied on its head and jaws rather than grasping. Many reconstructions suggest it was a quick, agile hunter capable of accelerating rapidly—well-suited to chasing prey in relatively open terrain.
Why Carnotaurus Matters
Carnotaurus helps paleontologists understand abelisaurids—predators that were especially successful in the southern continents. Its unusual body plan, combined with rare skin impressions, makes it one of the most informative large theropods ever found.
