Abavornis
Abavornis is the name given to a genus of primitive birds from the Late Cretaceous, containing the single species A. bonaparti. It was probably a member of the Enantiornithes, but as it is only known from a single broken coracoid, which, however, looks typically enantiornithine, that assignment is tentative. The fossil is from Late Cretaceous Bissekty Formation in the Kyzylkum, Uzbekistan. Another partial coracoid is very similar and is referred to as Abavornis sp.; it might belong to A. bonaparti and if so show some features which are damaged in the holotype.
