Recasting the Sangoan Stone Age Techno-Complex in the Stone Age Nomenclature at Sango Bay, Southern Uganda

Abstract

This paper discusses the complex use of the term ‘Sangoan’ and its placement between the Early Stone Age (ESA) and Middle Stone Age (MSA) using data from Simba Hill in Sango Bay. The purpose is to examine whether the Sangoan is Acheulean, Middle Stone Age, or an independent lithic industry at Sango Bay. Four specific objectives guided the study: reviewing the Stone Age terminology, Sangoan lithic typology, technology, and environmental characteristics. A detailed literature review of the Stone Age nomenclature shows patterns and trends of the Sangoan terminology; while a combined lithic assemblage from the archaeological surface survey and excavation yielded heavy and light-duty lithic tools. The 13 sites identified within the 202.6km surveyed had 73 lithic artefacts, while the excavation unit yielded 1344 lithic artefacts. The results suggest that the Sangoan typology at Sango Bay has five general lithic categories of shaped tools, backed pieces, cores, and debitage. Typologically, the conventional Sangoan lithics at Sango Bay include lanceolates, picks, cleavers, discoids, becs, points and core axes. Technologically, the Levallois lithic reduction strategy characterises the Sangoan with unifacial and bifacial retouch and core technology elements. The toolmakers at Sango Bay used local raw materials, suggesting they were not highly mobile in terms of raw materials. Conclusively, therefore, the Sangoan is a transitional lithic industry.
