Therizinosaurs and Ginkgo trees
Prehistoric life: Therizinosaurs are a strange offshoot of the theropod dinosaurs. Although most Mesozoic theropods were carnivorous, Therizinosaurs were herbivores.
Their large, sickle-shaped claws (which give the group its name: Greek therizo meaning “to cut” or “to reap” and sauros meaning “lizard”) were probably used to pull down tree branches much like the claws of extinct giant ground sloths.
