title: Preceramic occupations in the orinoco river valley.
abstract: Two sites in the Orinoco Valley containing preceramic from excavated contexts are described. Radiocarbon dating and stylistic comparisons indicate that the northern tropical lowlands were inhabited at the onset of the Holocene, suggesting a time depth of 9000 years before the present for tropical forest-savanna adaptations in northern South America.
