Terminal Pleistocene Lithic Technology and Adaptation from Bulbula River B1s4 Site, Ziway-Shala Basin, Ethiopia
Author(s): Abebe Taffere
Archaeological excavation which had been conducted in 2009 and 2010 in the Ziway- Shala Basin, close to the Bulbula River Canyon at B1s4 site, has yielded lithic assemblages and few faunal remains. Two human occupation horizons (PS1 and PS2) were identified which are separated by an occupational hiatus at the very end of the terminal Pleistocene. Analysis of debitage on both unit levels indicates the presence of similar features that lead us to assume that B1s4 lithic industry was oriented towards the production of blades and bladelets. But, this site shows strong technological and industrial variabilities to early Holocene sites which are very close to B1S4. The microliths, which are widely discovered at early Holocene sites and to a lesser extent sites dated to Pre-Glacial Maximum, are hard to find at B1s4.Alike Paleoenvironmental records in the Ziway-Shala basin and other parts of Ethiopia and Eastern Africa, B1s4 has proved that terminal Pleistocene was characterized by fluctuating weathering conditions that might have forced hunter-gatherers in the region to practice diverse adaptive strategies.
