Utahraptor was a bipedal, predatory dinosaur which lived in North America during the Cretaceous Period. It was the largest member of its family and also the most primitive. It was also a relative of Velociraptor, Deinonychus, Pyroraptor, Troodon, and Dromaeosaurus. It was a powerful and intelligent predator that hunted its prey by using a mix of intelligence and force. It was also very fast despite its gigantic size, since it had very long and slender hindlimbs and a long tail for balancing. It used its claws to attack its prey. Like other members of its family, it was bird-like and was covered in feathers.
