Description
Summary:ABSTRACT. Nine radiocarbon dates on five genera of Quaternary mammals from north-em North America are discussed. Of particular interest are: (a) a 29,000-year-old artifact from the Yukon Territory: (b) the first evidence that steppe mammoths (Mammuthus. columbi or M. armeniucus) occupied eastern Beringia during the peak of the Wisconsin glaciation; (c) dates indicating that saiga antelopes (Saiga ratarica) and Yukon short-faced bears (Arcrodus simus yukonensis) occupied the Yukon-Alaska region in mid-Wisconsin time: (d) dates indicating that bison (Bison sp.) lived near the arctic coast of the Northwest Territories, and tundra muskoxen (Ovibos moschatus) lived in the western Yukon in late postglacial time; and (e) dates suggesting that tundra muskoxen have occupied the central Canadian Arctic Islands for the last 7000 years. RÉSUMÉ. Neuf datations au radiocarbone sont ici discutees; elles ont et6 obtenues pour cinq genres de mammifbres du Quaternaire des regions septentrionales de I’Ambrique du Nord. Les points particulibrement interessants sont: (a) un artefact date A 29,000 ans provenant du Yukon; (b) la premitxe preuve de la presence du mammouth des steppes (Mammurhus columbi ou M. urmeniucus) en Beringie orientale au maximum glaciaire du Wisconsin; (c) des dates indiquant que l’antilope saiga (Suigu rarurica) et l’ours à museau court du Yukon (Arcrodus simus yukonensis) occup&rent le Yukon et l’Alaska à I’epoque wisconsinienne moyenne; (d) que le bison (Bison sp.) vkcut prbs de la côte arctique des Temtoires du Nord-ouest, et que le boeuf musque de la toundra (Ovibus moschrus) habita l’ouest du Yukon & la fin de I’epoque postglaciare; (e) enfin, des dates suggkrant la presence du boeuf musque de la toundra dans les îles de l’Arctique Central canadien pour les derniers 7000 ans.
