ABSTRACT
Paleolandscapes of the first half of MIS 2 or the Last Glacial Maximum (LGM) were reconstructed based on the study of the first mammoth fauna locality found in the Abakan River valley and a comparison with other localities of the South Minusinsk Basin. Sediments of the Uytag geological section under study included silt interlayers underlain and overlain by sandstone rock slack fragments and were interpreted as weakly eroded diluvium. Studies of the Uytag locality made it possible to clarify the time and range of distribution in southern Siberia for several mammals (Ovis ammon, Equus ferus, Marmota baibacina, Sicista subtilis, Lagurus lagurus, and Microtus gregalis) and the Pleistocene bird Aquila chrysaetos. The age of the locality was confirmed by radiocarbon dating. The species composition of the Uytag fauna was similar to that of other localities of the same age and region. All known localities and single finds of faunal remains indicate that open steppe landscapes were widely developed in the South Minusinsk Basin during the LGM.
