To the Definition of Technological Contexts Completeness of in Stone Industry from Cultural Layer 3 of Late Paleolithic Site Strelka-1 in Krasnoyarsk (On the Example of Side Scrapers)

Purpose. The Strelka-1 site is located in the historical center of Krasnoyarsk where the Kacha River flows into the Yenisei River. Cultural layer 3 of the site dates back to the Upper Paleolithic period and contains numerous items made of stone and organic materials – fragments of animal bones, wood, and bone ashes. Based on the evidential interpretation of one of the categories of stone implements (side scrapers), the authors assume that some of the tools were brought to the site in a ready-made form, some were made and used on site, and some were made and taken away. Results. The side scrapers with traces of intensive processing were of the highest production value. Three of these scrapers showed traces of general non-utilitarian wear – a consequence of their transportation in some loose soft packing. The implements of other types were mostly produced and utilized locally. The separation of three groups of stone implements according to their place in the complete knapping cycle allows us to clarify the quantitative and qualitative assessment of knapping purposes, the stages of tool processing, their purpose, as well as the duration of use. Conclusion. Such a method is aimed at studying specific archaeological sites as objects of a certain purpose and at determining the functional type of individual concentrations that we have identified within the boundaries of the cultural layer. The studied collection of stone products of cultural layer 3 reflects the dynamic processes of accumulation of a complex of material remains – the processes of accumulation of fragments of stone splitting sequences of various completeness in a limited area of the terrain.
