Flamingoes are well attested in the fossil record, with the first unequivocal member of the extant family Phoenicopteridae, Elornis known from the Late Eocene. A considerable number of little-known birds from the Late Cretaceous onwards are sometimes considered to be flamingo ancestors. These include the genera Torotix, Scaniornis, Gallornis, Agnopterus, Tiliornis, Juncitarsus and Kashinia; these show a mix of characters and are fairly plesiomorphic in comparison to modern birds. (The supposed “Cretaceous flamingo” Parascaniornis is actually a synonym of Baptornis and not a close relative to any living bird). An extinct family of peculiar “swimming flamingos”, the Palaelodidae, are believed to be related to, or to be the ancestors of, the modern flamingos. This is sometimes rejected, since the fossil Elornis is known from some time before any palaelodid flamingos have been recorded. There exists a fairly comprehensive fossil record of the genus Phoenicopterus.
