Theropods are a group of bipedal dinosaurs known for their carnivorous diet. They belong to the clade Dinosauria and are characterized by their hollow bones and three-toed limbs. Famous examples include the Tyrannosaurus rex and Velociraptor. Theropods are believed to have evolved into modern birds, making them an important part of the evolutionary history of avian species. These dinosaurs varied in size and shape, ranging from small, agile hunters to large predators. Theropods were primarily land-dwelling creatures, but some adapted to different environments. Their fossils provide valuable insights into the behavior and ecology of prehistoric life on Earth.
