The Loufangzi site, located in the eastern Gansu province, is an open-air site dated at the middle paleolithic. In 2018, excavations were carried out on the lower part of the cultural layer (Layer 14 and 15) of the Loufangzi site, and plenty of artifacts and animal bones were discovered in 16 m2. Lithic raw materials were made of gravel from river nearby, which were mainly quartz sandstone and siliceous limestone. The lithic assemblage includes cores, flakes, tools, chunks etc. The principle flaking technique was direct hard-hammer percussion. Most of tools were retouched by hard-hammer. The typological and technological characteristics of artifacts from the lower cultural layer of the Loufangzi site belonged to the small tool technology. Combined with the stratum accumulation and related pollen analysis, we preliminarily think that the age of lower cultural layer of the Loufangzi site is equivalent to MIS5.
