Gigantoraptor is a genus of the giant oviraptorid theropod dinosaur from the Late Cretaceous.



Gigantoraptor was discovered in 2005 in the Iren Dabasu Formation, Erlian basin, in Inner Mongolia. The age of the Iren Dabasu formation is controversial. Based on ostracods, Godefroit suggested the unit was Nemegt equivalent or about 70 MYA, although some dinosaur remains suggest an older Baynshirenian age c 85-90 MYA.

At 8 m long and 4 m tall it was one of the biggest oviraptorosaurids in Earth's history; its' American relative Chirostenotes is much smaller. Otherwise, Gigantoraptor was very similar to its smaller relatives, and it was possibly feathered as well.
