摘　　要：本文主要是对贵州兴义猫猫洞遗址出土的人化石进行的初步研究,并对哺乳动物化石、地层、堆积物作叙述。该遗址的人类化石包括下颌骨4件,股骨3段,是中国南方洞穴遗址中发现的数量较多,系统分类地位较清楚的晚期智人的化石。人类化石同层的鹿牙作铀系法测年结果为14500±1200 BP,相当于更新世的末期。This paper is a preliminary study of human and mammalian fossils unearthed from Maomao cave（25°10′N,105°02′E）,a rockshelter-type cave site located at the hillside of Maomao mountain,1.5 km to the southwest of Dingxiao township,or some 25 km to the southeast of Xingyi County,Guizhou Province.The human fossils consist of four mandibles and three femoral fragments.The mandibles include a complete female jaw,an incomplete male jaw,an anterior fragment of a child＇s jaw and a right fragment of a female jaw.Half of the jawbone has two mental foramens that are mainly located between P2M1.The mental foramen of another sample GM7504,however,is located at P2.These features are similar to those of other Late Pleistocene human fossils in China.Their morphological features are quite similar to those of the No.101 mandible of the ＂Upper CaveMan＂ from Zhoukoudian.Of the preserved mandibles,two possess a double mental foramen and one has only a single mental foramen.Only one of the three femoral fragments is well preserved,and of this specimen,the bone wall is very thick and the measurements are similar to those of the Ordos man and Hsiatsaowan man.The overall shape of the jawbone of GM7502 from Maomao cave is close to Late Pleistocene Homo sapiens in East Asia,especially the Upper Cave man（female） and Garden Hole man,but distinctive from Linde Mindanao people and Mengzi Red Deer cave people who shared close geographical locations.The measurements and index of the middle of thigh bones show that they more closely resemble Late Pleistocene Homo sapiens,and some features are even closer to that of human beings from Holocene site nearby.Meanwhile,the primitive nature is also prominent in forms of thick bone wall and small medullary cavity of the thigh bone.These jawbones and their teeth of Maomao cave site have the following characteristics.The chins of the human fossils are protruding,without mandibular torus;The mental spine has an evident progressive nature of tubercle shape and is protruding;The mental forame
