Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S.-A. Ji et al. 2011 | Qiliania graffini is distinguished from other presently known enantiornithines by its posses- sion of the following autapomorphies: distal quarter of pubis deflected ventrally; tibiotarsus very long and slender, with mid-shaft mediolateral width to proxi- modistal length ratio of less than 0.05 and proximo- distal length 133% that of femur; tibiotarsus with craniocaudally elongate and subrectangular proximal articular surface, well-developed cnemial crest, and deep distolateral fossa; and tarsometatarsus very long and slender (63% of proximodistal length of tibiotarsus). The taxon is further diagnosed by the following unique combination of apomorphies that occur, individually or in subsets, in other enantiorni-
thine taxa: deeply excavated medial epicondylar depression and shallower lateral epicondylar depres- sion on the distal tibiotarsus; distinct fibula fully fused to tibiotarsus; plantarily excavated tarsometa- tarsus; pedal unguals and associated keratinous sheaths relatively straight; and pedal ungual IV reduced (see Comparisons). |
