C. Gao et al. 2008Small (Table 1) non-pygostylian bird characterised by having the unique combination of the following characters: edentulous jaws; 13–14 differentiated caudal vertebrae; a strut-like and proximally expanded coracoid; an imperforate humeral deltopectoral crest; and a manual phalangeal formula of 2-3-3-x-x with the largest claw on digit I and subequal claws on digits II and III. The condi-tion of having a hand with an unreduced (clawed) digit III with three phalanges is unique among birds.
