| L. H. Hou 1997 | The parietal is posteriorly located, frontal is narrow and expanded posteriorly. Cervicals have a ventral keel, thoracic centra are amphiplatyan with elongated centra and relatively large lateral pleurocoels, and caudals are unfused to represent a relatively long tail. Proximal humerus is larger than on Cathayornis, is laterally expanded, there is a relatively large circular depression at its proximal midsection, and shaft is straight. Coracoid is relatively narrow and small with a linear distal terminus. Furcula is slender and the furcular process is extremely elongated. Tibiotarsus is slender and long and talons are large and recurved. |
