Lithic industry of the middle to upper Paleolithic boundary of Rubas-1 site (Maritime Dagestan)

The article presents stratigraphie descriptions and technological and typological study of lithic industry from excavating area 4 (2014 year) and pit 1-5 (2006-2007 years) of the Paleolithic site Rubas-1 in Dagestan. Nine lithological layers containing 7 culture-bearing horizons were complete recorded in pit 1. Sources of raw material are discussed. The Rubas-1 upper technocomplex is characterized by numerous simple flat cores as well as by distinct Levallois flake and point cores recorded in the lower horizons. The toolkits of all the archaeological horizons are presented by tools with scraping edges and notch-denticulate implements forms predominantly. The tools of the Upper Paleolithic categories are indistinct and are represented primarily by atypical scrapers and borers. Taken together these findings indicate that the site is dated to the Late Middle Paleolithic or Early Upper Paleolithic.
