About: Zhylgaia

Zhylgaia is a genus of birds known only from fossils. Its remains have been recovered from a Late Cretaceous or Paleogene deposit in Central Asia. The relationships of this genus are unknown; it was initially placed in the Presbyornithidae, which at that time were believed to be some sort of "transitional shorebird". Upon recognition that the presbyornithids were more likely a prehistoric lineage of fairly advanced waterfowl, Zhylgaia was assigned to the form taxon "", an assemblage of Late Cretaceous and Paleocene shorebirds which are not a natural clade but merely an assemblage of superficially similar birds. All that can be said about this taxon is that it was a modern bird, most likely a neognath.
