Dunhuangia
''Dunhuangia'' is a bird genus, belonging to the Enantiornithes, which during the Early Cretaceous lived in the area of present China. In 2015, Wang Min (palaeontologist), Wang Min, Li Daqing, Jingmai Kathleen O'Connor, Zhou Zhonghe and You Hailu named and described the type species ''Dunhuangia cuii''. The generic name refers to the city of Dunhuang in Gansu province. The specific name (zoology), specific name honours preparator Cui Guihia.M. Wang, D. Li, J. K. O'Connor, Z. Zhou and H. You. 2015.

Enantiornithes
The Enantiornithes, also known as enantiornithines or enantiornitheans in literature, are a group of extinct avialans ("birds" in the broad sense), the most abundant and diverse group known from the Mesozoic era. Almost all retained teeth and clawed fingers on each wing, but otherwise looked much like modern birds externally. Over eighty species of Enantiornithes have been named, but some names represent only single bones, so it is likely that not all are valid. The Enantiornithes became extinct at the Cretaceous–Paleogene boundary, along with Hesperornithes and all other non-avian dinosaurs. Discovery and naming The first Enantiornithes to be discovered were incorrectly referred to modern bird groups. For example, the first known species of Enantiornithes, ''Gobipteryx minuta'', was originally considered a paleognath related to ostriches and tinamou. The Enantiornithes were first recognized as a distinct lineage, or "subclass" of birds, by Cyril A. Walker in 1981. Walker mad ...
