摘　　要：广西扶绥县南山洞发现人类化石及哺乳动物化石。人类化石包括2枚智人牙齿化石,分别是左下第三臼齿和右下第二臼齿,其形态特征与广西其他山洞发现的智人化石相似,归入晚期智人。哺乳动物化石多为华南大熊猫———剑齿象动物群成员,时代属更新世晚期。该地点新发现的蒙古野驴化石属华南晚更新世动物群的首次发现。南山洞所有化石发现于洞内浅褐色砂质粘土中,堆积物第二层钙板层的铀系年龄为30—40ka。蒙古野驴的出现暗示中国南方大陆可能在末次冰期出现过干冷的气候环境。Human teeth and mammalian fossils were unearthed at Nanshan cave of Fusui County,Guangxi Zhuang Autonomous Region.The human teeth include a left lower M3 and a right lower M2.Their morphological features are similar to that of late Homo sapiens unearthed from other caves in Guangxi,belong to late Homo sapiens. Most of the mammalian fossils are members of Ailuropoda(-Ste-)godon fauna in south China. However,Equus hemionus is a new record of late Pleistocene fauna in this district.All the fossils in Nanshan cave were collected from brown fine sandy-clay.Ages of U-series dating on the second flow-stone are around 30 to 40 ka.The appearance of Equus hemionus suggests that the south China mainland had possibly ever been cool climate at the latest glacial period.
