Description: A blue-grey clay loam lens with plant and insect remains was found in an expo-sure of the Ob River, 2 km upper Dubrovino village in Novosibirskaya Oblast of Russia.Conventional radiocarbon dating of the Dubrovino deposit is ca 19,444±159 14C BP(23,234±338 cal yr BP) and coincides with Sartan glaciation period (MIS 2). Ninety-twoColeoptera species, dominated by fragments of Curculionidae and Carabidae are rep-resented in the Dubrovino deposit. Species of the tundra-steppe fauna are dominant,followed by meadow-dwelling taxa and coniferous forest taxa. A comparison of theDubrovino assemblage with the previously studied late Pleistocene Kalistratikha andBunkovo fossil assemblages showed that tundra-steppe landscapes with coniferousgroves and sparse meadow vegetation were typical for this area from the end of Kargininterglacial (MIS 3) through the end of the Sartan glaciation (MIS 2).
