Abstract: Daxingtun Upper Palaeolithic site is situated at 18 kilometres south-east of Angangxi District of Jijihaer County, Heilongjiang Province and had been excavated in 1981 and 1982. In 1986, we made a survey of this site again and found two new localities.
The materials collected include mammal fossils, stone artifacts and a bone tool. Among the fossils, Cervus sp. and Muntiacus sp. have not been found in this site before. A piece of bone on which show striken marks is identified as a bone utensil. The stone artifacts, mainly made of flint, are composed of cores, flakes, blades and tools. Most of them are very small in size and some are microliths. The tools are subdivided into the convex side-scraper, straight-convex scraper, end-scraper and micro-point. A few of them show fine workmanship.
