Therizinosaurus, the "Scythe lizard," was, surprisingly enough,  likely a herbivore despite its  intimidating exterior. With a  maximum length of ten meters and a  maximum height of four or five  meters, this freakishly tall  monstrosity possessed a terrifying  defining feature: incredibly long  claws that reached the length of a  meter. These claws likely provided  ample protection from the ferocious  predators that dared to prey upon  Therizinosaurus. As the last and  largest of the therizinosaurs, this  odd animal roamed the lands only a  few million years before the large  dinosaurs disappeared from the  Earth. Because of that, it serves as  the poster-child for its family,  Therizinosauridae.   Roaming what is now modern Mongolia, Therizinosaurus was among other odd herbivores and carnivores in  scrublands near deserts. However,  sometimes dense rainforests with  plentiful plantlife and a variety of  trees provided a suitable habitat  and wealth of food to  Therizinosaurus. Its monstruous  claws were used to reach branches  and leaves and pull them to its  mouth. It may have competed with  its relative Deinocheirus for food, though this would likely have been more of an issue in the desert than the rainforest.
