Also, studies have shown that the Therizinosaurs were actually Maniraptorans (not weird sauropods like they were thought to be when they were first discovered), due to the hip alignment of the creatures.
It is known only from a few bones, including gigantic hand claws, from which it gets its name. Therizinosaurus 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 ('reaping lizards'). It could grow up to 10 meters (33 feet) long and reach 5 tonnes in weight. Therizinosaurus, meaning 'scythe lizard' from the Greek 'therizo' meaning 'to reap' or 'to cut off' and 'sauros' meaning 'lizard') was a very large therizinosaurid (previously known as segnosaur). Therizinosaurus cheloniformis, as it appears in The Isle.
