Gigantoraptor was the largest Oviraptorosauria (egg-thief) Theropod Dinosaur from Mongolia in the Late Cretaceous. They were in the same family as Oviraptors.
Andy met a nesting pair of Gigantoraptors in some sand dunes. Other Theropods like Oviraptors and Alectrosaurus were trying to steal from the nest, but the mother scared them off. (APA: Gigantoraptor and Feather)
Andy saw some Gigantoraptors doing a mating dance just like modern birds do. Later one picked up Andy for dinner but he got pepper in its face and the dinosaur sneezed Andy back to the Old Museum Clock. (APA: Gigantoraptor and Tumbleweed)
