Chirostenotes and the larger Anzu, lending support to their hypothesized relationships. These bones can be distinguished from Chirostenotes and contemporary "Leptorhynchos" elegans by features of the limbs, specifically the hand and metatarsals. A new Chirostenotes specimen described by Funston and Currie (2020) preserving a mandible provides further evidence that Caenagnathus is a distinct genus from Chirostenotes despite both taxa being part of the Caenagnathidae.
