Carnivorous dinosaurs, also known as theropods, were meat-eating reptiles that roamed the Earth during the Mesozoic Era. They had sharp teeth and claws, which helped them hunt and consume other animals. Some well-known examples include Tyrannosaurus rex and Velociraptor. These dinosaurs varied in size, from small, agile hunters to massive predators. Many carnivorous dinosaurs were bipedal, meaning they walked on two legs. They played a crucial role in their ecosystems as top predators, helping to maintain the balance of animal populations. Fossil evidence shows that they had keen senses, which aided in their hunting strategies.
