Abstract: In 1991, the first excavation was taken in the cave site of Luoshayan in Fengkai county. The archaeological remains consist of quite a few stone artifacts, a large number of mammalian fossils including nearly forty species, and four fossil human teeth. Here are some major points: First, the findings of Luoshayan prove the existence of Paleolithic culture in Guangdong province. Second, its cultural relics fill the gap of prehistoric culture from 20,000 B.P. to 100,000 B.P. in South China. Third, this excavation provides information for investigating the cultural transition from Paleolithic age to Neolithic age in Guangdong, and provides new materials to study cultural relationship between Southeast Asia and South China.
Finally, the fauna of Luoshayan contributes more data to the systematic study of Stegoden-Ailuropoda Fauna in South China. Furthermore, the result of this research shows more evidence of the changes of ecological environment in this area.
