Lithics, landscapes & la Longue-durée – Curation & expediency as expressions of forager mobility

摘要: Abstract With the recognition that practically all archaeological sites are depositional composites unrelated to activities of any contemporaneous group individuals (i.e., palimpsests) and forager adaptations not ‘site-specific’ but rather landscape-scaled phenomena, statistical approaches designed take these predicates into account have been developed over past 20 years depart from traditional techno-typological systematics used for decades in much Europe Levant. Based on artifact density frequency retouched pieces scaled volume sediment excavated cave rock shelter sites, – surface ratio artifacts totals unit area, they can potentially determine whether or changes mobility land-use often assumed coincided with major evolutionary events (e.g., Middle-Upper Paleolithic transition) actually occurred. Lithic counts densities La Riera (Posada de Llanes, Asturias, Spain) here illustrate potential approach. Changes volumetric then compared a radiocarbon summed probability curve using calibrated BP dates against oxygen isotope ratios GISP2 ice core. The intent is what extent macroclimatic change 30–10 ka cal interval compares sequence.
