Raw material procurement as a crucial factor determining knapping technology in the Katta Sai complex of Middle Palaeolithic sites in the western Tian Shan piedmonts of Uzbekistan

Abstract

This paper presents the results of the study of raw material procurement on two late Middle Paleolithic sites, Katta Sai 1 and Katta Sai 2, located in the western Tian Shan piedmont. The previous studies allowed to identify an unknown Levallois variant of human cultural adaptation in the regional Middle Paleolithic. Predetermined flake technology focused on obtaining the thin triangular flakes or even blades. At the same time, the river pebbles of effusive rocks brought from the nearby river gorges were used for knapping. The paper analyses the sources of the raw material collected, and its knapping quality together with the technological features indicating how the manufacturing scheme was adjusted to the quality of used raw material.
