Population mobility and lithic tool diversity in the Late Gravettian – The case study of Lubná VI (Bohemian Massif)

Abstract

This paper presents the results of excavations conducted at the Late Gravettian site of Lubná VI in 2012 and 2018. This site is an exceptional example of a short-term Late Gravettian campsite, occupied between 27.5 and 27.1 ka cal BP. Due to the specific location of this site, in an area situated far from lithic raw material sources, the archaeological remains offer a rare possibility to understand the subsistence strategy of highly mobile hunter-gatherers in the Late Pleistocene. The knapped lithic assemblage is composed of erratic Cretaceous flint imported over long distances, and the tool inventory is typical of Late Gravettian assemblages from Central Europe, with a dominance of burins and backed implements. However, the lack of chert and flint raw material in the vicinity of the site inspired the occupants to use bladelet blanks to make hunting weaponry from burin spalls. This specific behaviour is unique among Gravettian inventories known from the western Carpathians. Reindeer dominate the faunal assemblage over other species. The season of occupation at Lubná VI was probably early autumn, and may be associated with the maximum use of environmental resources by the hunter-gatherers. The small campsite was located at a convenient spot for processing reindeer carcasses, where some hearth stone constructions were arranged. Because there was no woody vegetation in the closest vicinity of the site, reindeer bones and fat were used as fuel in hearths. Given the lack of nearby flint raw materials, the accessibility of large numbers of reindeer near Lubná, probably present on a seasonal basis, explains the occurrence of Late Gravettian occupation in this micro-region.
