New data of late Pleistocene occurrences with megafauna in the Chumysh (Altai region) and Chick rivers (Novosibirsk region)

This article is summarized a few study results of the large-scale localities of Late Pleistocene megafauna on the Chumysh (Altai Territory) and Chick (Novosibirsk region) Rivers in 2011-2014. Redeposited osteological remains of the 22 species in the amount of 4636 were collected on the Chumysh beaches and 1320 large mammals remains of 16 species were found on the Chick riversides. Radiocarbon dating showed the Kargin age (W-2) for the most of mammal bones from the both locations. The findings of Cuon alpinus, Bos primigenius and Stephanorhinus kirchbergensis on the Chumysh River, C. crocuta spelaea on the Chumysh River and Chick River are of greatest interest. Apparently, bone remains of the S. kirchbergensis occur in the Initial Late Pleistocene sediments. The megafauna lived under predominance of the forest-steppe landscape in Chumysh area and under the steppe landscapes associated with relatively warm conditions closed to modern climate in Chick area.
