Collecting of the theriofaunal materials at the rivers Chumysh (Altai region) and ob near Bibikha village (Novosibirsk region) in 2015

2,3 k magafaunal remains have been collected or registered on the beaches and sand banks of the Chumysh river (Altai region) in 2015. The total amount of the osteological assemblage, collected at the Chumysh in 2011-2015, is close to 7 k of the bone remains related to 23 large mammal species. Redeposited faunal remains specifically hail from the lowermost parts in the cross-sections of the second terrace above the flood-plain. They ate dated to the first half of Late and Middle-Early Pleistocene. The bison (44,4 %) and equine (21 %) bones are predominated. The number of deer and carnivore remains add up to 9,8 % and 1,7 % respectively. The first phalanx of camel Knoblochi found near Zarinsk town is of substantial interest. It is the second finding of his remains at the Prealtaian plain for the last centenary. This finding reflects that Camelus knoblochi episodically spread far northward from his home steppe areal. The significant occurrence with redeposited bone remains was discovered at the sand bank of the Ob River near Bibikha village (Novosibirsk region). More than 950 bones of 13 species of large mammals were collected here in 2015. The remains have the asynchronous geological age, but the most of them can be related to the Middle Pleistocene on the ground of the range of attributes. The measurements and ratio rating of the equine metapodias and full measurements of the bison bones specifically indicate it. Bibikha is the fifth occurrence at the south part of Western Siberia, where soergelia (Soergelia cf. elisabethae) remains were found. As it can be see according to species composition the theriofaunae of Karginsky time from Chumysh river and Middle Pleistocene from Bibikha, respectively, existed in predominant steppe landscape.
