Abstract
The 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 in the Abakan River valley and comparison with other localities in the South Minusinsk Basin. The sediments in the geological section of Uytag are represented by interlayers of silts, underlain and overlain by sandstone rock slack fragment, interpreted as weakly eroded deluvium. The study of the Uytag locality made it possible to clarify the time and range of distribution in southern Siberia of some mammal species Ovis ammon, Equus ferus, Marmota baibacina, Sicista subtilis, Lagurus lagurus and Microtus gregalis, as well as Pleistocene bird Aquila chrysaetos. The age of the locality is confirmed by radiocarbon dating. The species composition of the fauna is similar to other localities in the region of this age. All known localities and single finds of faunal remains indicate a wide development of open steppe landscapes in the South Minusinsk Basin during the LGM.
