Gigantoraptor
The diet of Gigantoraptor is uncertain. Although some oviraptorosaurs such as Caudipteryx and Incisivosaurus are thought to have been mostly herbivorous, Gigantoraptor had long hind legs with proportions that allowed for fast movement, and large claws, a combination that is not usually found in herbivores of this size. Paul suggested that Gigantoraptor also was a herbivore and used its speed to escape predators.
