Caenagnathidae is a family of derived caenagnathoid dinosaurs from the Cretaceous of North America and Asia. They are a member of the Oviraptorosauria, and relatives of the Oviraptoridae.[2] Like other oviraptorosaurs, caenagnathids had specialized beaks,[3] long necks,[4] and short tails,[5] and would have been covered in feathers. The relationships of caenagnathids were long a puzzle. The family was originally named by Raymond Martin Sternberg in 1940 [6] as a family of flightless birds. The discovery of skeletons of the related oviraptorids revealed that they were in fact non-avian theropods,[7] and the discovery of more complete caenagnathid remains [4][8] revealed that Chirostenotes pergracilis, originally named on the basis of a pair of hands, and Citipes elegans, originally thought to be an ornithomimid, named from a foot, were caenagnathids as well.
