The article presents stratigraphic descriptions, technological, and typological studies of archaeological materials of upper complex of artifacts obtained from test-pits 1–5 (2006–2007) and excavation area 4 (2014). Sources of raw material are discussed. The upper complex of artifacts from Rubas-1 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, spike-like and notch-denticulate implements predominantly. The tools of the Upper Paleolithic categories are indistinct and are represented primarily by atypical end-scrapers, borers etc. Archaeological materials from the archaeological horizons 1–3 lack any indications of Levallois technology and could be attributed to the transitional industries. It is confirmed with the materials of lower archaeology horizons (4-7) characterized with the use of the techniques of primary reduction similar to those of the Upper Paleolithic recorded at many Middle to Upper Paleolithic Transition sites in Europe and Near East (Stránská Skála, Boker Tachtit). Thus, the industry of the upper complex Rubas-1 is a transition within the Middle - Upper Palaeolithic and takes the interval within 50-35 kyr BP. These estimates do not contradict with the results of other science-based studies.
