Therizinosaurus had huge claws on its forelimbs that measured up to 70cm long, so would have been a fearsome sight. It was originally described from only a few bones discovered in Mongolia which were at first thought to belong to a turtle-like reptile and not a huge theropod dinosaur! As a Therizinosaurus skull has never been found, there is no definitive evidence as to what this clawed beast ate. However, since it had close relatives known to be herbivorous, it's likely that Therizinosaurus too was a plant-eater. Its terrible claws were probably used to strip bark from trees or fend off predators and rivals.
