Stone industry of the upper artificial complex from the Rubas-1 site (based on the excavated materials of 2015)

The article presents the new data for stratigraphy of the excavation area 5 and technological typological analysis of the archaeological materials which were got during the excavation of the Rubas-1 site in 2015. Stone industry was analysed on the ground of the generalize data. Taking to account the collections of the 2006-2014 the materials of excavation area 5 give the opportunity to mark out two groups of assemlages according with archaeological levels 1-3 and 4-8. These collections have the special differences as in primary flaking technique well as in the tool assemblages. The developed Levallois technique used with the parallel unidirectional or bidirectional core reduction marks the stone industry of the group from the lower levels (4-8). The scrapers dominate in the tool assemblage. Cores and Levallois spalls are absent in the artificial complex of upper level, the percent of the facetted striking platform slumps. It is possible to characterize a tool assemblage in the light of materials excavated during the last years. They demonstrate the dramatic increase and Upper Paleolithic tool type variability, scrapers and burins mainly, and the presence of chisel-like and truncated tools. The common differential peculiarity of the entire industry is a great number of chips and debris and their employing as the blanks. Proceeding from the general estimation of industry from the archaeological levels 4-8 it is possible to conclude that this archaeological complex corresponds to Terminal Middle Paleolithic stages according to set of attribute. Levels 1-3 can mark the Initial stage of transition to Upper Paleolithic.
