Abstract: The Dagudui mountain prehitoric stone tool workshop was discovered in October 1984 by the authors. The site is located on the western range of the Taer mountain near the Shanugou village, N 35o 50' 28, E 111° 29', about 7 kilometres to the west of the well-known Dingcun site. The stone artifacts are massively accumulated around the site and numbered about tens of thousands. The cultural layer is 4 metres in the thick part and covered over the whole slope of the mountain. The raw material is greyish black metamorphic rock, obtained directly from the underneath bedrock. The stone flakes are the main component of the assemblage. The cores are mainly irregular in shape, and the representative of the regular cores is the funnel- shaped core, but small in number. All tools are made by direct knapping inethod, and most of them are made of flakes. They are divided into three major types: chopper, scraper and point. The point could be also subdivided into 6 kinds: short flat point, long sharp point, shoulder-shaped spearhead, spear-shaped point, triangular point and duckbill-shaped point. The spear-shaped point is a kind of new implement so far discovered in the region. No polished stone tools have been found. The Dagudui assemblage is regarded as a new regional cullure in North China. The age of the Dagudui mountain culture is estimated between the end of the paleolithic age and the early period of the neolithic age.
