Carnotaurus sastrei

Carnarotaurus was a distinctive and fearsome theropod dinosaur that roamed South America during the Late Cretaceous period, about 70 million years ago. Characterized by its unique, bull-like features, it had a short, deep skull with thick, horn-like structures above its eyes, which may have been used for display or combat with rivals. Growing up to 9 meters (30 feet) in length, Carnotaurus had a slender, lightweight body, with powerful, muscular hind limbs that suggest it was a fast runner, likely capable of chasing down prey. Its arms were incredibly short—among the smallest relative to body size of any known theropod—leading some scientists to speculate that it was a highly specialized predator that relied on speed and agility rather than strength or grappling with its prey. Fossil evidence indicates that Carnotaurus likely hunted smaller dinosaurs and possibly scavenged, using its powerful jaws, filled with sharp, serrated teeth, to tear through flesh. Its unique combination of adaptations, including its horns, slender build, and specialized locomotion, set it apart as one of the most specialized and visually striking predators of the Cretaceous ecosystems.
