Dietary diversity in the Atacama desert during the Late intermediate period of northern Chile

Quaternary Science Reviews, 2019
Abstract The Pacific Ocean that flanks the hyperarid Atacama Desert of Northern Chile is one of the richest biomass producers around the world. Thus, it is considered a key factor for the subsistence of prehistoric societies (including mixed-economy groups), that inhabited its coastal ecosystems as well as the neighboring inland areas.
