Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. H. Hou 1997 | Presence of an acute and hooked beak, sternum with slender elongated lateral process with slight distal expansion, carina undeveloped as a low crest, torso noticeably reduced posterior to the acetabulum, proximal ischium with dorsal process, pubis distinctly posteriorly extended with a strong curvature and distal end booted, distal tibiotarsus intercondylar vacuity extremely compressed and in distal perspective the anterior margin of the medial condyle is relatively flattened. Only the proximal end of the tarsometatarsus is fused, the midsection is distinctly narrow, MtIV is relatively slender and weak, trochleae of the other three metatarsals lie nearly on the same plane, the pes unguals are longer than the phalanges and are strongly recurved with acute termini, and the pygostyle is elongated. | |
| J. M. O'Connor et al. 2011 | A small enantiornithine bird characterized by the unique combined presence of the following morphologies: premaxilla rostral to external nares imperforate with parallel dorsal and ventral margins; dorsal surface of premaxilla with slight concavity just rostral to the nasal processes; premaxilla with large, recurved teeth; large and robust pygostyle 20% longer than tarsometatarsus; metatarsals II–III subequal in length and ending distally at approximately the same level; metatarsal IV longer than II and III and laterally deflected along the distal one-fifth of the tarsometatarsus (modified from Zhou & Zhang, 2006) |
