 Obi-Rakhmat's finds share features of both the late Middle Paleolithic and the early Upper Paleolithic artifacts of Southwest Asia and the Altai Mountains.It appears that the Upper Paleolithic in the Altai emerged from a local Middle Paleolithic culture established in the area around 100,000 to 50,000 years ago.Based on material of the most recent excavations from 2007 to 2009 there is reason to assume that the Obi-Rakhmat lithic artefacts represent a transitional Middle-to-Upper Paleolithic industry.
