Don't let the Wolverine-like claws fool you. Unlike the X-men's most popular pugilist, this new dinosaur species was no predator, scientists say. Dubbed Nothronychus graffami, the 13-foot-tall (4-meter-tall) therizinosaur (reconstructed skeleton pictured) lived about 92.5 million years ago in what is present-day Utah. N. graffami's claw bones are 9 inches (23 centimeters) long. But in life, sheathed in hornlike keratin, the talons would have each been about a foot (30 centimeters) long.
