Duonychus tsogtbaatari, a 90-million-year-old fossil found in the Gobi desert, may be the closest thing the dinosaurs had to Edward Scissorhands. It was a bipedal, herbivorous animal that had only two fingers on each hand, which it may have used to grasp branches and pull them towards its mouth. But they were no ordinary fingers, as they were armed with two giant claws up to 30 centimetres long that belie its vegetarian diet.
