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.

Therizinosaurus (/θɛˌrɪzɨnɵˈsɔrəs/; 'scythe lizard', from the Greek therizo meaning 'to reap' or 'to cut off' and sauros meaning 'lizard') is a genus of very large theropod dinosaurs. Therizinosaurus comprises the single species T. cheloniformis, which lived in the late Cretaceous Period (late Campanian-early Maastrichtian stages, around 70 million years ago), and was one of the last and largest representatives of its unique group, the Therizinosauria. Fossils of this species were first discovered in Mongolia and were originally thought to belong to a turtle-like reptile (hence the species name, T. cheloniformis — "turtle-formed"). It is known only from a few bones, including gigantic hand claws, from which it gets its name.
