水洞沟遗址位于宁夏回族自治区银川市以东28千米处,西距黄河18千米,距离灵武县城30千米,处于银川盆地东部边缘。水洞沟第12地点(以下简称“SDG12”)地理坐标为北纬38°19′40″,东经106。29′49″,海拔1158米,地处水洞沟第1地点以北约4千米处。2007年夏,中国科学院古脊椎动物与古人类研究所联合宁夏文物考古研究所对其进行了约12平方米的发掘,收获石制品近万件。石制品的技术分析显示,细石叶技术是SDG12的核心技术因素,SDG12古人类的原料利用策略具有计划性
Shuidonggou site is located in Yinchuan City, Ningxia Hui Autonomous Region 28 km east of the Yellow River, 18 km west of Lingwu County, 30 km from the edge of the eastern Yinchuan Basin. The geographic coordinates of Shuidonggou No.12 (hereinafter referred to as “SDG12”) are 38 ° 19’40 “north latitude, 106.29’49” east longitude and 1158 meters above sea level, Rice Department. In the summer of 2007, the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences and Ningxia Institute of Archeology and Archeology unearthed about 12 square meters of them, harvesting nearly 10,000 pieces of stone products. The technical analysis of stone products shows that the fine stone leaf technology is the core technical factor of SDG12 and the raw material utilization strategy of SDG12 ancient human is planned
