| Реферат: | eng: The description of the sediment section of the first floodplain terrace of the Bija River gives in this paper and new data on the fossil fauna of Mokhovo location in the Republic of Khakassia. The fauna location is associated with channel alluvium sediment at the base of the section of the Bija river terrace. The channel alluvium is overlain by floodplain sediments and alluvial soils. This fauna location is one of the few alluvial fauna locations in this region. The large mammals fauna is represented by wooly mammoth Mammuthus primigenius, horse Equus ferus, argali sheep Ovis ammon, buffalo Bison priscus, red deer Cervus elaphus, saiga antelope Saiga tatarica and roe deer Capreolus capreolus, the small mammals are represented by the remains of Lagurus lagurus, Microtus sp. and Spermophilus sp. A morphological study of bone remains was performed. The wooly mammoth from Mokhovo location can be attributed to a thick enamel form, close to the mammoths of the Karginian horizon from Kuznetsk Basin. The roe deer from the Mokhovo location are close to roe deer of the Karginian horizon from Tunka rift. The argali sheep from Mokhovo location is smaller than the Pleistocene argali of the Minusinsk depression and is close to the average size of recent animals from Altai. The horses from this location can be classified as short stature and small horses. The only roe deer and red deer have survived of the large mammals in the region is currently. The large mammals species composition of the Mokhovo locality is closest to the fauna of the Uzunzhul locality, for which the Karginian horizon is assumed, and is very different from the Sartanian horizon fauna in the localities of the region. The radiocarbon dating from the argali sheep skull was obtained and is confirmed the age of the fauna of the Mokhovo locality. The large and small mammals fauna data are indicate the predominance of steppe and forest-steppe landscapes in the region during the formation of alluvial deposits of the first floodplain terrace of the Bija River. These deposits were formed in the late Karginian time. The similar landscape conditions are typical for the Bija River valley at present.
