Oviraptorosaurs are a group of feathered maniraptoran dinosaurs from the Cretaceous period of what are now Asia and North America. They have short, beaked, parrot-like skulls, with or without bony head crests. They ranged in size from "Caudipteryx", which was the size of a turkey, to the 8 meter long, 1.4 ton "Gigantoraptor". The most complete oviraptorosaur specimens have been found in Asia. The North American oviraptorosaur record is sparse.
