title: A Successor of Tepexpan Man in the Valley of Mexico.
abstract: A preceramic site at San Vicente Chicoloapan, in the Valley of Mexico, disclosed a human burial associated with stone-lined hearths and artifacts. The prevalence of primitive grinding stones suggests a collecting economy of the "Chalco culture," now for the first time recognized as such, and belonging to a long-headed people that succeeded Tepexpan Man some 8000 to 6000 years ago.
