Utahraptor

As you might have guessed from the name, the therapod dinosaur Utahraptor first lived in the Utah region of the western United States during the early Cretaceous period. 5m long and weighing around 300kg, Utahraptor is one of the biggest – and slowest - genera in the dromaeosauridae family. Unable to outrun most smaller dinosaurs, this genus relies on its sickle claws and a powerful bite to ambush its prey.
