摘要：In building the foundation for a reservoir in the western suburb of Tong-lian county, Si-chuan province, in summer 1976, the workers, the peasants and we there discovered numerous mammalian fossils, the plant fossils and more than 300 pieces of artifacts in the sand layer about 8 meters below the land surface. C¹⁴ tests on some plant fossils associated with the artifacts and the mammalian fossils show that they date back to 21550±310 or 25450±850 B.P.
    The present paper deals with a brief study of the artifacts in situ. The study of plants and mammalian fossils in the locality and stratigraphy nearby will be given by us in other paper.
