Mammoths live until 3700 years ago

This doesn’t take anything away from “Lost Giants” (Charles Q. Choi, Scientific American, Feburary 2010, p. 21) but megafauna persisted well after 13,700 years ago. In Europe, the dramatic contraction in mammoth range occurred about 12,000 years ago. A mastodon at the Manis Site in Washington was dated to 12,000-11,000 years, and drarf mammoths have been dated to about 3,700 years ago on Wrangel Island, Siberia, and to 7,900 years ago on St. Paul Island, Alaska. The Manis mastodon had a stone point embedded in a rib.
