摘　　要：2001年对镇江莲花洞进行了第二次考古发掘,从洞内首次获7件石制品和一批哺乳动物化石.5件石核和2件刮削器分别用石英和火成岩制成,初步判断属于旧石器时代中期或稍早,文化面貌似与上世纪末在苏南地区发现的旧石器早、中期文化略有不同.根据对第2、3堆积层间的新生碳酸盐岩并参考动物化石的铀系年代测定,主要含化石的第2层年代应在～100-300 ka之间,相当于中更新世晚期到晚更新世早期.由地层堆积、出土石制品和动物化石等埋藏情况分析,莲花洞不是人类的长期居址,很可能只是一处临时停留地.Paleoanthropological locality Lianhua Cave (119°04′10″ E, 32°06′02″ N) is situated in the southern suburb of Zhenjiang City, Jiangsu Province. This site was first excavated in 1981, having recovered a hominid fossil molar (m2) associated with mammalian fossils of 15 species. During the second excavation organized in late 2001, 7 stone artifacts and more than 700 pieces of mammalian fossils were discovered.Stratigraphically, the deposits of more than 4 meters in thickness can be divided into 4 layers. The cultural relics and mammalian fossils were unearthed from the layers 2 and 3, which are 1.7 m thick brown sandy clay and 2 m thick brownish red sandy clay respectively.The stone artifacts, including 1 percussive and 4 bipolar cores, and 2 scrapers, are made of quartzite and igneous rocks. They bear features different from those known in southern China.According to U-series dating of calcite and animal teeth samples from layers 2-3, the age of the hominid fossil and stone artifacts should be in the range of～100-300 ka, i.e. late Middle Pleistocene/early Upper Pleistocene.Based on the features of deposits, and rarity of human remains, we suggest that the Lianhua Cave was a temporary living locality only.
