Abstract
To estimate the age of the glaciation in the New Siberian Islands, fossils of small mammals from the Sana-Balagan site (Faddeevsky Island, Russian Eastern Arctic) have been studied. The evolutionary degree of this fauna, which indicates the age of the sediments underlying the glacial deposits, suggests that the glaciation of the New Siberian Islands began no earlier than 190–210 thousand years ago. The new biochronological data in combination with 230Th/234U dates show that the geological event in question was synchronous with the Moscow glaciation or the Moscow stage of the Dnieper glaciation (the Vychegda glaciation, the final stage of the Saalian, the final stage of the Riss, the end of the MIS 6, 180–140 thousand years ago).
