Aythya is a genus of diving ducks. It has twelve described species. The name Aythya comes from the Ancient Greek word αυθυια, aithuia, which may have referred to a sea-dwelling duck or an auklet.[1]
Aythya shihuibas was described from the Late Miocene of China. An undescribed prehistoric species is known only from Early Pleistocene fossil remains found at Dursunlu, Turkey;[2] it might however be referrable to a paleosubspecies of an extant species considering its age (see also Greater scaup).
The Miocene[verification needed] "Aythya" arvernensis is now placed in Mionetta, while "Aythya" chauvirae seems to contain the remains of two species, at least one of which does not seem to be a diving duck.[3]
