La excavación arqueológica en el abrigo rocoso Guayabero I, considerada como la primera investigación estratificada de un sitio precerámico en la Amazonia Colombiana, registra la presencia del hombre prehistórico a partir de c.a. 7000 A.P. Las lascas prismáticas, concoidales, triangulares y retocadas; y en menor frecuencia los raspadores circulares, discoidales y laterales, todos instrumentos de tipo Abriense recuperados de una capa de suelo arenoso pardusco, son evidencia de una ocupación precerámica en el sitio entre el 5000 y 2000 A.P. La reducida muestra de fragmentos cerámicos encontrados en los niveles más superficiales de la excavación, por su similaridad, recuerda las tradiciones cerámicas encontradas en las localidades de Araracuara y La Pedrera (región Amazónica). Muestras de polen, y análisis de semillas, ocre y resinas ampliarán esta primera evidencia de cazadores -recolectores en la región tropical de la Amazonia Colombiana.
Archaeological excavation at the Guayabero I rock-shelter, considered the first stratified investigation of the preceramic period in the Colombian Amazonia, reveals human presence since c. a. 7000 B.P. in the region. The Abrian type prismatic, concoid, triangular and retouched flakes, and the less abundant, terminal, disk-like, lateral and circular scrapers recovered from a brownish sandy soil are evidence of a preceramic occupation between 5000 and 2000 B.P. Scarce ceramic fragments found at the uppermost levels of the excavation, due to their similarity, only suggest possible relationships to ceramic traditions of the Araracuara and La Pedrera localities, within the same Amazon region. Pollen, seeds, ochre, and resins analysis will probably expand this first evidence of hunter-gatherers in the eastern tropical lowlands of Colombia.
