Evidence of specialized resource exploitation by Modern Humans in Western Iberia associated to Pleistocene and Holocene extreme environmental conditions

Throughout prehistory, landscapes were repeatedly subjected to both global and localized climatic fluctuations that changed the regional environments where human groups lived. This instability demanded constant adaptation and, as a result, functionality of some sites over time. In this light, western coast Iberia represents an exceptional case study due proximity between at least oceanic cores archaeological sites, which should facilitate accurate reconstruction relationships paleoenvironmental conditions coeval patterns behavior. region, in particular valley River Lis, is marked by wide exposed plateaus cut narrow deep canyons. paper we present stratigraphic, archaeometric, technological archaeobotanical record Poço Rock Shelter, located one these canyons, hints responses such changes, discuss link its Solutrean Epipaleolithic occupations specific activities. During coldest part Last Glacial Maximum, hypothesize there was intensive exploitation chert outcrop above roof produce blades tips. Later, during Bond Event 6, after had been exhausted, consumption shellfish gathered mouth canyon sea. We strikingly different roles demonstrate how hunter-gatherers adapted local conditions, exploited resources, promising provide better understanding about functional role extreme climate events.
