“…It is useful to compare the fossil insect fauna identified from the Dubrovino site with fossil assemblages from other sites in the central and southern parts of the West Siberian Plain (Figure 1) (Zinovyev, 2006(Zinovyev, , 2016Zinovyev et al, 2016;Dudko et al, 2017;Gurina et al, 2018). The closest assemblage, in terms of chronology and locality, is from the Novaya Surtaika site on the right bank of the Isha River near its confluence with the Katun River in the foothills of the Northern Altai (52°14' N, 85°55' E; 21,389±400 14 C BP [SPb-2299] and 18,248±250 14 C BP [SPb-2415], or 25,648±603 cal yr BP and 21,918±390 cal yr BP).…”

“…The species composition of the Dubrovino assemblage is similar to that of the Kalistratikha (52°58' N, 83°37' E; the end of MIS 3: 24,438±350 14 C BP [SPb-1416] or 29,222±567 cal yr BP) and Bunkovo (55°04' N, 82°30' E; the end of MIS 2: 11,550±125 14 C BP or 13,515±398 cal yr BP) assemblages. Phytophagous beetles, especially the weevils Otiorhynchus altaicus (= O. karkaralensis Bajtenov, 1974) and O. ursus (= O. kasachstanicus Arnoldi, 1964), dominate these assemblages (Zinovyev et al, 2016;Gurina et al, 2018). The meadow complex is poorly represented, dominated by O. politus.…”

“…Late Pleistocene insects are known from deposits on the southern part of the West Siberian Plain and have recently been described from sites in the territory of Novosibirskaya Oblast and Altaiskii Krai (Tsepelev et al, 2013;Zinovyev et al, 2016;Kuzmina, 2017;Gurina et al, 2018). One of the fossil deposits was discovered in the bank of Ob River near Dubrovino Village (ca 55°27′ N), with calibrated radiocarbon age of 23,234±338 cal BP (SPb-1417), that coincides with Marine isotope stage 2 (MIS 2) and the Sartan glaciation period according to Siberian regional scale.…”

A blue-grey clay loam lens with plant and insect remains was found in an exposure 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 14 C BP (23,234±338 cal yr BP) and coincides with Sartan glaciation period (MIS 2). Ninety-two Coleoptera species, dominated by fragments of Curculionidae and Carabidae are represented in the Dubrovino deposit. Species of the tundra-steppe fauna are dominant, followed by meadow-dwelling taxa and coniferous forest taxa. A comparison of the Dubrovino assemblage with the previously studied late Pleistocene Kalistratikha and Bunkovo fossil assemblages showed that tundra-steppe landscapes with coniferous groves and sparse meadow vegetation were typical for this area from the end of Kargin interglacial (MIS 3) through the end of the Sartan glaciation (MIS 2).

“…The species composition of sub-fossil insects from the sites Kizikha-1 and Kizikha-2 are extremely different. Only three species occur in sub-fossil assemblages of both sites, two species, Otiorhynchus altaicus (= O. karkaralensis Bajtenov, 1974) and O. ursus (= O. kasachstanicus Arnoldi, 1964), are common residents of sub-fossil assemblages in southern and central parts of West-Siberian Plain Zinovyev et al, 2016;Gurina et al, 2018Gurina et al, , 2019.…”

“…More than 130 sites with insect remains of different ages from Pleistocene to Holocene are known from this territory (Zinovyev, 2008(Zinovyev, , 2011Sheinkman et al, 2016;Rusakov et al, 2019). In a course of the expedition trips 2012-2014 in southern part of West Siberian Plain insect remains were found on banks of rivers Ob, Chik, Suzun, Chumysh, Alei, Ustianka and Kizikha (Tsepelev et al, 2013;Tshernyshev et al, 2013;Gurina et al, 2016Gurina et al, , 2018Gurina et al, , 2019Zinovyev et al, 2016). These studies increase our knowledge about late Pleistocene entomofauna of West Siberian Plain and indicating patterns of changes in insect assemblages along latitudinal -zonal gradient.…”

Two sites with insect remains were found in an exposure on the bank of Kizikha river, in the Rubtsovskii District of the Altaiskii Krai of Russia, Kizikha-1 with radiocarbon age 13455±150 14 C BP (SPb-1347), and Kizikha-2 with the age 26094±400 14 C BP (SPb-1418). This period is coincides with Sartan stadial and Kargin interstadial (MIS 2 and MIS 3). This is the southernmost late Pleistocene insect bearing deposit found in West Siberia. The fragments in both sites are represented mainly by Coleoptera. Beetle fauna from the site Kizikha-1 is represented by 34 species from 9 families. The majority of fragments belong to weevils and ground beetles. 28 species from 8 families are found in Kizikha-2 site, the majority of fragments belong to Carabidae. 7 species found in the sites, Dyschiriodes rufimanus, Cymindis cf. rostowtzowi (Carabidae), Cidnopus cf. parallelus, Pristilophus punctatissimus (Elateridae), Hemitrichapion alexsandri (Brentidae), Paophilus albilaterus and Otiorhynchus sushkini (Curculionidae), are recorded in Pleistocene deposits for the first time. Sub-fossil insect assemblages of the two sites coincides with the late Pleistocene "Otiorhynchus-type" sub-fossil insect fauna from southeastern part of West-Siberian Plain (Zinovyev, 2011; Legalov et al., 2016) with characteristics as follows: dominance of steppe species, presence of halophile species, lack of forest species. Most of these species are absent in the contemporary regional fauna. The complex of eastern species and presence of endemics of Altai-Sayan Mountain system is also characteristic to the both studied sites. Specifics of the deposit assemblages in comparison with the other late Pleistocene fauna of West Siberian Plain is in high share of meadow species that could be explained by taphonomic condition of sedimentation or microclimatic conditions caused by close location to Altai mountains. Analysis of sub-fossil insect fragments showed that open landscapes with zonal steppe and sparse meadow vegetation near rivers and in depressions were typical for this area. In comparison to contemporary conditions climate was dry and cold, but Kizikha-2 (end of MIS 3) was formed in more mild climate conditions than Kizikha-1 (end of MIS 2). Results gained from Kizikha-1 and Kizikha-2 sites are complementing data on latitudinal-zonal distribution of beetles found in late Pleistocene deposits in West Siberian Plain.
