With two-fingered hands and long "nasty" claws, the Duonychus tsogtbaatari is certainly a strange sight. Fossils of this dinosaur were recently unearthed in Mongolia's Gobi Desert while a water pipeline was being constructed. Scientists say the Duonychus was a member of a group of "some of the weirdest dinosaurs ever".
