Abstract

This article presents the first complete data on finds of mammals of the mammoth fauna in the Upper Yana basin (Verkhoyansk region (Verkhoyansky Ulus), Oldzho River)). A list of mammal species from the locality on the Oldzho River is compiled. Eleven mammal species are identified. Bighorn sheep are recorded in the Upper Yana area for the first time. The 14 C age of the locality is over 49 thousand years. Most likely, it was formed during from the onset of the Karginsky (MIS 3) interstadial This geological age is also indicated by a few bones of species such as musk ox and reindeer. The geomorphology of the locality differs from the typical permafrost sections in the north of the Yana–Indigirka Lowland. The bone bed of the Oldzho locality occurs in the yedoma polygenetical deposits of the 50-m terrace. The erosion terrace socle is composed of bedrock sandstones and argillites, weathered to the state of coarse-grained eluvium in the upper part. Neopleistocene deposits are represented by humified loess-like loams with peat interlayers and plant detritus inclusions, which are overlain by a 4–4.5 m thick ice wedge in the upper part of the section. The bone bed lies at the base of loess-like loams. It is quantitatively dominated (in descending order) by the bones of bison, horse, woolly rhinoceros, and red deer. There are all age groups of herbivorous mammals. Predators (cave lion, brown bear, wolf) are only represented by adult individuals. Pathologies of the limb bones of herbivorous mammals, caused by traumatic injuries, were relatively commonly recorded.
