A moveable feast: Variation in faunal resource use among central and western North American Paleoindian sites

In the Great Plains and Rocky Mountains of North America, researchers have debated the degree to which Paleoindian foragers relied on large-game hunting to fulfill their subsistence needs. This study reviews the zooarchaeological record from 60 sites to test predictions drawn from prey choice models. Results indicate that different site types provide different perspectives on Paleoindian faunal use. Data from kill assemblages can only inform on the exploitation of large game, while the full variety of prey used by Paleoindian foragers is represented at camp localities. In addition, prehistoric foragers varied prey choice based on habitat setting. In the low diversity grasslands of the High Plains and Rolling Hills, prehistoric groups hunted large game almost exclusively. In the more diverse environments of the alluvial valleys and foothill/mountain environments, foragers show higher diversity of faunal use. During the early Holocene, small game made a greater contribution in the diet of Paleoindians, possibly in response to changing environmental conditions and/or increased hunting pressure.
