The Utahraptor could grow up to 7 meters (20 feet) long and weigh almost a ton. A close relative of the Velociraptor, this dinosaur was a fierce predator. Like other dromaeosaurids, it had a huge, blade-like claw on its second toe. With this 20 centimeter talon, it is believed that the Utahraptor could make a deep cut 5 to 6 feet long with one swipe, enabling it to kill dinosaurs much larger than itself.
