Abstract
Paleoindian fluted point distribution in the contiguous United States is analyzed for possible sampling biases. Potential sample biases examined in this article include modern population, years since statehood, acreage in cultivation, and intensity of urban and residential development. Results suggest that at the state level Early Paleoindian fluted point samples are correlated with modern population, years since statehood, and acreage of urban development. A regression model developed to account for significant sampling biases demonstrates that regardless of sample biases several states in the Eastern United States have an overabundance of predicted Early Paleoindian fluted points. Sampling biases do not appear to affect fluted point varieties dating to the Middle Paleoindian period. Land cover characteristics are examined using principal components and cluster analyses in an effort to define biogeographical associations with fluted point types and possible environmental sampling constraints.
