摘　　要：The late Precambrian algal megafossils, Chuaria-Tawuia assemblage, were found for the first time in Bed 6 of the Shilu Group, Hainan Island, South China. Consequently. the geological age of the iron-ore deposits of the Shilu Group can be determined and placed into the Qingbaikou System. This meaningful discovery offers sufficient evidence for settling the protracted dispute over the ore-forming age of the Shilu iron deposits, and will be of great help for better understanding the evolutional history of geology and tectonics, as well as the further ore-prospecting of the Shilu-type iron-deposits both in the island and South China.The late Precambrian algal megafossils, Chuaria-Tawuia assemblage, were found for the first time in Bed 6 of the Shilu Group, Hainan Island, South China.
