Convergence at Poverty Point: a revised chronology of the Late Archaic Lower Mississippi Valley

Abstract

AbstractThe Poverty Point site, located in the Lower Mississippi Valley of the south-eastern United States, is commonly considered a centre of innovation that exported new material culture, practices and identity to presumably contemporaneous sites in the region. Recent radiocarbon data, however, show that Jaketown, previously interpreted as a peripheral expression of Poverty Point culture, is earlier than the type-site. Using the revised chronology at Jaketown as a case study, the authors argue that assuming a radial diffusion of cultural innovations biases our understanding of social change and obfuscates complex histories. Their study demonstrates how examining local sequences can challenge generalised models of regional cultural change.
