Carnotaurus was a large theropod dinosaur that lived during the Late Cretaceous period, approximately 70 million years ago. It is notable for its distinctive features, including a pair of thick, bull-like horns above its eyes, and a deep, robust skull with a shorter snout compared to other theropods. Carnotaurus was a bipedal predator, characterized by a sleek body and small forelimbs, and it is believed to have been a fast and agile hunter, preying on smaller dinosaurs and other animals in its South American habitat.
