We describe a new enantiornithine specimen Dunhuangia cuii, gen. et
sp. nov., from Lower Cretaceous Changma Basin, northwestern China.
Dunhuangia cuii represents the second enantiornithine to be named from
ornithuromorph dominated Changma avifauna.
Phylogenetic analysis place Dunhuangia cuii in a derived position with


We report on a new enantiornithine bird, Dunhuangia cuii, gen. et sp.
nov., from the Lower Cretaceous Xiagou Formation of the Changma Basin,
northwestern China. Although the material is incomplete, Dunhuangia
cuii preserves unique coracoidal and sternal morphologies that
distinguish it from other known enantiornithines; this specimen
represents only the second enantiornithine reported from the Changma
Basin that is diagnostic at the species level. This study enriches our
understanding of the enantiornithine component of this
ornithuromorph-dominated, Early Cretaceous avifauna.
