ФУНКЦИОНАЛЬНЫЙ АНАЛИЗ ОБРАБОТАННОГО НЕПОЛНОГО РОГОВОГО СТЕРЖНЯ ДЗЕРЕНА PROCAPRA GUTTUROSA ИЗ ПЯТОГО КУЛЬТУРНОГО СЛОЯ СУХОТИНСКОЙ МАСТЕРСКОЙ

Abstract

The article is devoted to the functional analysis of the tool of Procapra gutturosa Mongolian gazelle, made on an incomplete horn rod, found during excavations in 2019. The Sukhotinskaya workshop has been known since the 1970s. For the first time it is mentioned in the scientific reports of I.I. Kirillov as a place of collection of numerous lifting material. For the first time, a test pit at the site was laid in 2013, and in 2019 it was expanded. In the course of these works, at the base of the section, a processed horn rod of Procapra gutturosa of an average degree of preservation was found, which was subjected to functional analysis. In the course of studying the object under binocular and metallographic microscopes, five microsections were identified on the largely destroyed treated surface of the horn rod, which retained individual areas of focal micropolishing and thin linear traces directed along the axis of processing. The direction vector of these microtraces coincides with the visual profile of the horn rod processed into a wedge by cutting. These areas are preserved on the heights of the furrowed surface in places where the bone substance of the horn shaft has not undergone significant changes. Of particular interest are individual microchip of hornfels and micaceous rock/pyrite, which are stuck directly in the bone substance at an angle of about 30°, which clearly indicates the angle and direction of processing. Based on the results of the functional analysis of the tool, an extraordinary tool was determined, carrying two generations of trimming by cutting off the knocked-off edge.
