Abstract: The Dayao Paleolithic site is located near Dayao village, northeastern Hohhot, Inner Mongolia Autonomous Region, and include eight gullies and some caves. In 2011, the Erdaogou Locality was discovered in the second gully and excavated from June 21 to September 1 in the same year by staff of the Institute of Vertebrate Paleontology and Paleoanthropology and the Inner Mongolia Museum. An excavated area of about 50m2 was exposed. This paper examines one aspect of stone technology of the Erdaogou Locality, namely core reduction.
An analysis of cores, flakes, flake fragments and tools reveals that there exist three types of flaking? technique? at? the? EDG? Locality,? namely? direct? hammer? percussion,? systematic? knapping? technology and the microblade technology. Direct hard hammer percussion is the principal flaking technique, and three core reduction strategies by direct hammer percussion can be inferred from various cores forms, namely directional flaking, alternate flaking, and multi- directional ?flaking.? These ?three? flaking? strategies ?are? guessed ?to? be ?employed? to? exploit ?pebbles? with different initial shapes and sizes.
