Gigantoraptor is an extinct genus of giant oviraptorosaur from Late Cretaceous Mongolia, 71 to 65 million years ago.
About 26 ft (8 m) long and weighing as much as a car, this enormous Oviraptorosaur is far bigger than any of its known relatives. Like all oviraptorasaurs, Gigantoraptor almost certainly had long, flamboyant feathers on its arms.
