This book presents the multidisciplinary results of an extensive underwater excavation in north Florida. This yielded the most complete results of interactions between early Paleoindians and late Pleistocene megafauna, in a rich environmental context in eastern North America. The data provides fundamental insights into "the Peopling of the Americas" and "The Extinction of the Megafauna". An excellent color photo section expresses the uniqueness of this project.
