 The discovery of skeletons of the related oviraptorids revealed that they were in fact non-avian theropods, and the discovery of more complete caenagnathid remains  revealed that "Chirostenotes pergracilis", originally named on the basis of a pair of hands, and ""Ornithomimus" elegans", named from a foot, were caenagnathids as well.Overall, the anatomy of the caenagnathids is similar to that of the closely related Oviraptoridae, but there are a number of differences.In particular, caenagnathid jaws exhibited a distinct suite of specializations not seen in other oviraptorosaurs.
