- 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.
