Terminal Pleistocene/early Holocene 14C dates form archaeological sites in Chile: Critical chronological issues for the initial peopling of the region

Abstract A review of 14 C information for archaeological sites in Chile between 13,000 and 7000 BP assesses the consistency of information on the early settlement of the region. Results explore geographical distribution, contextual reliability, repeatability and cultural association of this assemblage of dates. Chronological trends are discussed through the use of averaged calibrated occupational events based on contextual and statistical data. The use of this database constitutes the framework for discussing critical issues such as the first consistent human presence, regional temporal peopling differences, the chronological data supporting consistent use of littoral environments, and the coexistence/interaction of extinct faunas and humans. Research biases and current unsolved questions are raised in order to formulate a future agenda for improving chronological data for the human occupation of the Pleistocene-Holocene transition in Chile.
