Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. H. Hou 1997 | Beak is slender and acute with an elongated and thin nasal process of
the premaxilla and short maxillary process. Five pair of teeth are present on both the premaxilla and the mandible. The mandible is slender and linear. Humerus is slightly shorter than the radiusulna with a relatively well developed pneumatic fossa and capital groove, dorsal and ventral tuberosity are extremely distinct, and shaft curvature resembles that on extant taxa. A manubrium is present on the sternum, as is a short anterolateral process, the carina is relatively well developed, and lengths of the posterior and posterolateral processes are equivalent. The distomedial condyle on the femur is enlarged, a cnemial crest is present on the tibiotarsus, and the talons have intense curvature |
