Data from human paleofecal samples can be used to address a variety of questions, primarily the reconstruction of diet, but also the analysis of nutrition, health, technology, and behavior Statistical analyses of constituents can be used to broaden the potential of paleofecal data, as well as to detail cuisine and to address larger issues of settlement/subsistence models. This potential is illustrated with a cluster analysis of paleofecal constituents from three late prehistoric period sites along the northern shore of ancient Lake Cahuilla, located in the Coachella Valley of southern California. These data were used to test competing settlement/subsistence models: one of large permanent lakeside villages dependent on lacustrine resources, and the other of seasonal, rather than permanent, lakeshore occupation. In addition, the analysis revealed additional details of diet and cuisine in the late prehistoric period.
