Diagnosis
ReferenceDiagnosis
D. -Y. Hu et al. 2012Xiangornis can be referred to Enantiornithes based on the following synapomorphies: ‘Y’-shaped furcula with elongated hypocleidium; coracoid with convex lateral margin and concave dorsal fossa; and minor metacarpal extending distally beyond major metacarpal. Differs from other enantiornithines in having the following unique combination of features: large size; coracoid with medially curved acrocoracoid process; proximally convex humeral head; carpometacarpus longer than coracoid and completely fused both proximally and distally; short alular metacarpal (about one-sixth of the length of major metacarpal) completely fused to major metacarpal; large flange-like extensor process; and intermetacarpal space positioned significantly distal to the alular metacarpal.
