The Paleolithic locality of Taizishan is located about 2 km to the north of Taizishan Forest Farm,Xianghua town,Xichuan county,Henan province,and is close to the Han River.In 2012,270 stone artifacts were collected from this locality,including mainly cores,flakes and tools,and a small number of chunks and bipolar products were found as well.The raw materials are mainly flint and quartzite,followed by limestone,quartz and quartz sandstone.The sizes are basicaly small and medium with only a few large ones.The flaking technique contains direct hard hammer freehand percussion and bipolar percussion.The tool types are mainly scraper made of flake blank,and meanwhile chopper,handaxe and pick by gravel blank also account for a relatively large proportion,which shows the combination of pebble tool industry in the South and the flake tool industry in the North.Based on the characteristics of stone artifacts and related geomorphological studies,the locality was dated to the late Paleolithic.Taizishan locality has found the largest number of picks and handaxes in the Dan River region so far;the combination of its location and the lithic cultural features of the Dan River and the Han River Basin suggests that the picks and handaxes in the Dan River Basin are influenced by those from the Han River Basin.
