In this paper, we present a zooarchaeological analysis of the Longshan period sites of Taosi and Zhoujiazhuang (ca. 2300–1900 cal. BC) in southern Shanxi Province, China. We compare the faunal record at both sites in terms of the proportions of wild and domestic taxa; the slaughter patterns for the main domesticates; the types of bones used to produce utilitarian and decorative bone artifacts; and the types of bones used for ritual oracle bone divination. Differences in the faunal records at Taosi and Zhoujiazhuang provide insights into the connections between specialization and early urbanism. Our research also provides clues about how sheep and cattle pastoralism was initially adopted in the Yellow River Valley during the late 3rd millennium BC. Copyright © 2015 John Wiley & Sons, Ltd.
