A claw found in Mongolia from the hand of an unknown dinosaur measured no less than 70 cm in length. As the horny outer part of the claw was missing, it would have been even longer. Almost nothing is known about the rest of this extraordinary animal, which has been given the name of Therizinosaurus. We do know that it was a theropod, and must have been a ferocious predator.
