Abstract
For the first time a very rich and diverse fossil assemblage was described from the Shine Us locality in south western Mongolia. The sample represents floodplain deposits of the Beger Fm., including aquatic and terrestrial fossils such as freshwater ostracods, fishes, gastropods, reptiles, birds, as well as thirty mammal species. The concentrations of disarticulated, mostly fragmentary bones and teeth are interpreted to be accumulations of small floodplain channels. The fossil composition of the Shine Us assemblage SHU-A/1 is broadly in agreement with well-dated mammal faunas of the “Amphechinus taatsiingolensis Abundance Zone” (= letter zone C) of the Valley of Lakes. There, radiometric and magnetostratigraphic datings suggest an early late Oligocene age for this Biozone. The estimated age of the Shine Us assemblage (SHU-A/1) is between 26 and 28 million years.
Key words: Oligocene, vertebrates, taxonomy, stratigraphy, Mongolia.
Systematic Palaeontology
Class Aves Linnaeus, 1758
Aves indet.
A very few and extremely fragmentary bird bones (NHMW 2018/0135/0000) were present
in the screen washing residue of the Shine Us sediments, but they allow no precise systematic assignment.
Order Accipitriformes Vieillot, 1816
Family Accipitridae, Vieillot, 1816
Accipitridae indet.
