白云洞位于江苏省徐州市九里区九里山的白云寺内，产有中国鬣狗，三门马，李氏野猪，葛氏斑鹿，肿骨鹿等9个种类，其地质时代大体上与汤山第一地点或北京人动物群同时，为中更新世晚期。

MAMMALIAN FOSSILS OF BAIYUNDONG CAVE AND LOC. 1 AT TANGSHAN IN NANJING

Mammalian fossils were collected from Baiyundong Cave (White Cloud Cave, 34°l7' N , 117° 18' E), Xuzhou, Jiangsu Province. The mammalian fauna in BaiyundongCave is sindlar to tha of Loc. l at Zhoukouian.The mammal fossils found from the cave contan 9 species belonging to 9 genera,7 families, 4 orders, as listed in Chinese text.Most of the species were also found at Loc. 1 of Tangshan (Xu et al., 1993;Mu et al., 1993).There are two mammalian faunas in Middle Pleistocene. On is the Chenjiawofauna, and the other is the Peking Man fauna or the Zhoukoudian fauna. TheChenjiawo fauna is the temperate Quateary fauna of the archaic type. Its geologicalperiod is correlared with Stages 14-29, ranging from 500 000 to 1 000 000 years ago.While the Peking Man fauna is the temperate Quaternary fauna of the evolved type.Itsgeological Period corresponds to Stages 6-13, ranging from 127 000 to 500 000 yearsago (Table 1). Cricehaus varians LSD is correlated with Event 9 in Amrica andEurope and marsk the first appearane of the Peking Man fauna in Zhoukoudian（Repenning， 1987；Xu, 1996）． So the geological age of the faunas at both BaiyundongCave and Loc. 1 at Tangshan corresponds to that of the Peking Man fauna.
