Early Paleoindian foraging: examining the faunal evidence for large mammal specialization and regional variability in prey choice

North American archaeologists have spent much effort debating whether Early Paleoindian foragers were specialized hunters of megafauna or whether they pursued more generalized subsistence strategies. In doing so, many have treated the foraging practices of early North Americans as if they must have been uniform across the continent, even though others have pointed out that adaptations appear to have varied among groups inhabiting different kinds of environments. Resolving these issues fully requires referring to archaeofaunal data and evaluating those data critically. In this paper, we conduct such an evaluation of the existing Early Paleoindian faunal record, which we then use to test the hypothesis that early Americans across the continent specialized in the hunting of megafauna. After detailed attention is given to taphonomic issues, to the limited geographical distribution of sites with secure associations between humans and prey taxa, and to differences among sites in the roles that they likely played in settlement and subsistence systems, it becomes clear that the faunal record provides little support for the idea that all, or even any, Early Paleoindian foragers were megafaunal specialists. It does appear, however, that there was considerable variability in Early Paleoindian prey choice across the continent, which was likely related to variability in the environments that different groups inhabited.
