A radiocarbon age determination of a tundra muskox (Ovibos moschatus) skull fragment from Jämtland, central Sweden gave an age of 44 000 ± 1500 14C years BP or c. 46-49 cal. ka, indicating that the species was a member of the Middle Weichselian fauna of Sweden. The age confirms that central Sweden was ice-free during parts of the Middle Weichselian, prior to the last glacial maximum, as shown by previous studies. The region was probably characterised by treeless arctic to subarctic tundra environments.
