Biziura lobata Shaw, 1796

Fig. 5C .

Material.—QM F1125 (partial left humerus), QM F1133 (left tarsometatarsus), and QM F7057 (left femur) from Chinchilla, Australia, Pliocene.

Remarks.— Olson (1977) referred species formerly assigned to Dendrocygna validipinnis and Biziura exhumata by de Vis (1888c) to the extant Musk duck, Biziura lobata . Olson (1977) noted that one specimen (QM F5551), supposedly from Chinchilla, had a different preservation, and might come from the late Pleistocene Darling Downs deposits.

Stratigraphic and geographic range.—Pliocene to Recent; Australia.

Genus Anas Linneaus, 1758

Type species: Anas platyrhynchos Linneaus, 1758 , Europe, Recent.

Anas superciliosa Gmelin, 1789 Fig. 5D .

Material.—QM F1122 (partial right humerus) and QM F5550 (left coracoid) from Chinchilla, Australia, Pliocene.

Remarks.— De Vis (1888c) described a new species of duck, Nyroca robusta , from Chinchilla. This species was considered by Olson (1977) to be indistinguishable from the living Pacific black duck, Anas superciliosa .

Stratigraphic and geographic range.—Pliocene to Recent, Australia, New Guinea, New Zealand, Indonesia, Pacific.

Genus Aythya Boie, 1822

Type species: Aythya marila (Linneaus, 1761) , Europe, Recent.

Aythya australis Eyton, 1838 Fig. 5A .

Material. —QM F1123 (left coracoid) and QM F1124 (left tibiotarsus) from Chinchilla, Australia, Pliocene.

Remarks.— Olson (1977), continuing his review of de Vis’s 1888c) ducks, referred two other Chinchilla species ( Nyroca recluse and Anas elapsa ) to the extant White-eyed duck Aythya australis .

Stratigraphic and geographic range.—Pliocene to Recent; Australia.
