Hunter-Gatherers of the High-Altitude Afromontane Forest - Holocene Occupation of Mount Dendi, Ethiopia Spatial Temporal
Presentation at SAfA 2018 Conference in Toronto: The Dendi Lake Rock Shelter is situated circa 80 km west of Addis Abeba on the West Central Ethiopian Plateau in the Ginchi woreda of the Oromiya regional state of Ethiopia. In October 2012 a team from the University of Cologne, CRC 806 directed by R. Vogelsang excavated a test-trench that revealed four archaeological horizons that could clearly be distinguished in typological manners as well as by radiocarbon dates. The talk will focus on the lithics,...
Radiocarbon-dating adhesive and wooden residues from stone tools by Accelerator Mass Spectrometry (AMS): challenges and insights encountered in a case study doi Spatial
In this study we present and assess a process to enhance archaeological residue AMS dating by focusing on contaminant confinement. The sequence of methods applied consists of: 1) optical residue and usewear analyses, 2) experimental designs addressing cleaning treatments to mitigate impact of contaminants, 3) preparation and extraction of residues from (mostly) previously dated stone artefacts, and 4) establishing the elemental characteristics of residues by using SEM/EDX as a final step to avoid sample...
