| Abstract: |
Stable carbon and nitrogen isotope ratios from 14C dated bones of early Atlantic aurochs (Bos primigenius Bojanus) and late Atlantic first domestic cattle (Bos taurus Linnaeus) in eastern Denmark and southern Sweden are significantly different and provide information on the origin and feeding strategies of the two species. Radiocarbon dates generally divide the bone material of aurochs and domestic cattle in three groups: aurochs older than 4000 cal yr BP, an older group of domestic cattle around 4000 cal yr BP, and a younger, less well-defined group of domestic cattle starting at around 3500 cal yr BP. The older domestic cattle are represented mainly by fragmentary bones left over from meals, and deposited in lakes at the vicinity of the settlement areas. Bones of the younger domestic cattle group occur both as settlement debris and as single articulated skeletons in bogs, commonly in association with different types of clay pots. The latter type of finds suggests that sacrifice of domestic cattle began at this time. The dating of the early domestic cattle further indicates that they were contemporaneous with or slightly younger than the elm decline, which occurred shortly after 4000 cal yr BC on the Danish island of Sjælland. Our results indicate a sudden rapid introduction of domestic cattle into Denmark, heralding the introduction of agriculture and there is no evidence for leaf foddering or domestication of aurochs. A combination of several natural events may have created the necessary open land, providing the grazing areas for the imported cattle.
