Passerine birds from two late Pliocene localities, Shaamar in northern Mongolia and Beregovaya in
Transbaikalia (East Russia), represent the first known Neogene fossil assemblages of perching birds from
Asia. A total of 11 families and 15 taxa are recognized, including a new genus and species of bunting,
Pliocalcarius orkhonensis, apparently related to the Longspurs, and new species within the genera Hirundo
and Rhodospiza, which are described. The avifauna is composed of open land and bush dwellers; it
contains a few arid species, representing the oldest finds of the corresponding genera or lineages. This
may indicate that the living Asian arid avian complex originated in Central Asia in the Neogene. Several
genera (Rhodospiza, Paradoxornis) are documented in this paper for the first time in pre-Pleistocene
deposits. Report of Calcarius is the first pre-Holocene evidence of the occurrence of this genus in Asia,
which together with the remains of Synaptomys lemmings at Shaamar, illustrates faunal interchanges
between North America and Asia in the Pliocene.

A new relatively large duck, Chenoanas deserta gen. et sp. nov. from the Middle Miocene of the Sharga locality, which is morphologically intermediate between the extant genera Chenonetta and Tachyeres, is described.

A new relatively large duck, Chenoanas deserta gen. et sp. nov. from the Middle Miocene of the Sharga locality, which is morphologically intermediate between the extant genera Chenonetta and Tachyeres, is described. The diversity of Early and Middle Miocene ducks is discussed. It is noted that some Middle Miocene duck remains are incorrectly referred to the genus Mionetta. The distribution of morphological characters of the humerus in Neogene and extant ducks shows that the present day diversity of ducks apparently results from extinction of some taxa which were formed in the Oligocene-Early Miocene. The distribution of morphological characters in the evolution of diving ducks is evidence that not only the formation of different morphotypes but also so-called “evolutionary maturation” of taxa also explains the modern diversity.

A new genus and two new species of ducks (Aves: Anatidae) from the Middle Miocene Sharga
locality are described. Mioquerquedula minutissima gen. et sp. nov. is a very small duck. Anas velox Milne

A new genus and two new species of ducks (Aves: Anatidae) from the Middle Miocene Sharga
locality are described. Mioquerquedula minutissima gen. et sp. nov. is a very small duck. Anas velox Milne
Edwards, 1868 from the Middle Miocene of France is transferred to the genus Mioquerquedula. Aix praeclara
sp. nov. described here is the oldest record of the modern genus Aix. A revision of the previously described
small duck Anas soporata Kurochkin, 1976 shows that only the specimens from the Sharga locality should be
referred to this species. The status of other small ducks from the Neogene of Europe and North America is
discussed. The diversity of herbivorous and diving ducks in the Sharga locality indicates that Miocene
Shargyn Govi Lake was rich in food resources.
