Abstract
The currant paper presents the preliminary results of the multidisciplinary study of the new Pleistocene section Ulan-Zhalga (51°29′40.75″ С, 107°20′18.11″ В) discovered in the Western Transbauikalaia in 2017. On the base of the paleontological, paleomagmetic, and lithological data the early, middle and late Pleistocene sediments were recognized in the section. The analysis of the rich small mammal fossils resulted in to trace the paleoenvironmental and climatic changes in the region during the Quaternary. The unique alternation of the 19 faunistic horizons and 11 fossil soils in the whole section, the high correlation of the paleomagnetic and paleontological data allow us to refer the studied section Ulan-Zhalga to addition new late Cenozoic Key section of the south Eastern Siberia. The new geological and paleontological data would be important for paleogeographical reconstruction and biostratigraphic analysis.
