This suggested that all of the ivory had 28 been scavenged from long-dead animals. However, a date of 11,540 ± 140 BP has been obtained on ivory collagen from Broken Mammoth, and another date of 12,060 ± 60 BP for ivory from Swan Point, indicating contemporaneity of living mammoths with the earliest human settlers. A recent Bayesian analysis of the Alaskan radiocarbon record suggests that the date of horse extinction is ca. 14,200 cal bp, “broadly contemporary with the arrival of humans in the area,” while extinction of woolly mammoth occurred later, ca.

At first glance, Guthrie’s dates would lead one to conclude that mammoths had gone abruptly extinct in eastern Beringia at 11,500 BP. , 1998). On Wrangel Island, off the north coast of Siberia, the last date for a small mammoth is 3,685 ± 60 BP. On St. Paul Island, one of the Pribilof Islands located in the Bering Sea, 500 km off the Alaska coast, dates of 7,908 ± 100, 8,015 ± 85, and 8,010 ± 40 BP were obtained for split samples of one mammoth bone (Guthrie, 2004).
