Abstract: The Zhangkou cave site of the Scenery of Jinxiang is situated about 40 kilometres north-east of Yiliang county, Yunnan province. The cave site was discovered in 1989 and was excavated in 1990. As a result 1826 pieces of stone artifacts, 25 species of animal fossils and three bone artifacts were obtained. They were found from the upper and lower groups of the deposits. The stone artifacts can be divided into hammers, anvils, cores, flakes, choppers, scrapers and gravers. Most tools are trimmed on the flakes. Stone tools with handle and cobbles with multiple pits are represented in the assemblage. The mammalian fossils associated with the stone artifacts from the lower group of the deposits belong to Ailuropada-Stegadon fauna. 14C date of the upper group of the site is 9965 ± 110y B.P. and of the lower group is 14550 ± 450y B.P. It seems that the assemblage from the Zhangkou cave site represents a new cultural type of late Paleolithic or Epi-Paleolithic in Yunnan province.
