To achieve the task, I have executed the distributional survey and sondage for site for three years in Mongolia. As the result, site of the transition period from Middle Paleolithic age to Upper Paleolithic age were discovered, and the site were excavated in year fourth. In the excavation, horse's teethes, rodent teethes and bones and ostrich's egg shells excavated along with stone implements such as blads, blad cores, scrapers and flakes. The results will become the valuable data in thinking about the approval process at Upper Paleolithic age in north Asia.
