Muskox bone found on Banks Island, NW Canada tells a story of a possible warm refugium in the cold Arctic Muskox Bone of Possible Wisconsin Age from Banks Island, Northwest Territories
ABSTRACT. Part of a metacarpal of Ovibos was found in 1963 on Banks Island, Northwest Territories, Canada, near 121"54'W., 73"23'N. The bone was indistinguishable from Ovibos moschatus. A Carbon-14 date in excess of 34,000 years was determined. The possible existence of a Wisconsin refugium on Banks Island is discussed. Evidence suggests that a refugium existed there isolated from Beringia. In addition to plant species, two small mammal species (Lemmus sibiricus and Lepus arcticus) and possibly muskoxen survived in the Banks Island refugium.
There's also the tricky question of how the ice age climate supported hundreds of thousands of mega-fauna north of the arctic circle!
