To clarify unanswered questions of site formation, geology and the archaeology of the Berelekh geoarchaeological complex, a special survey was undertaken in 2009 of the area surrounding the site. Several geological units have been revealed. By establishing the spatial and temporal relationship of these deposits—as well as their age—we have reconstructed the formation history of the Berelekh bone bed. The mammoth bone deposit belongs to a paleochannel. Radiocarbon dating of mammoth remains at Berelekh demonstrates rapid accumulation during the Bølling warming. Human involvement in its formation is, at best, questionable, since there is no real overlap between the radiocarbon dates associated with past human activity, and those of the mammoth bone bed. This study confirms that humans used mammoth bone remains after the bone bed was deposited. Culturally, the Berelekh “site” does not have any relationship to the so‐called “Dyuktai culture.” Instead, the Berelekh archaeological finds (side notched stone pendants) show certain similarities to non‐microblade terminal Pleistocene assemblages found from Yenisei to Kamchatka. Additionally, the Berelekh complex presents a clear analogy with lithics found in Eastern Beringia. Teardrop‐shaped incomplete bifaces found in the assemblage are comparable to the Chindadn points of Alaska. The nature of this “Chindadn connection” is intriguing but it is the only visible cultural link between Western and Eastern Beringia. 相似文献

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). 相似文献
