An undescribed prehistoric species is known only from Early Pleistocene fossil remains found at Dursunlu, Turkey[1]; 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 2 species, at least one of which does not seem to be a diving duck.[2]
