Description :
The purpose of this study was to characterize geochemical variability in the basal LMBII deposits and thereby identify freshwater settings within the otherwise saline and alkaline Eastern Lacustrine Plain. Data on stone artifact and fossil bone abundances in these same settings were used to test the fundamental prediction of the Olduvai hominid land-use model (Blumenschine and Peters, 1998). This model proposes that large-carnivore predation and frequent hominid scavenging opportunities near freshwater sources produced an associated focus of stone tool discard and loss.
