ResumoXitaiping Cave,a recently found Late Pleistocene locality,is the first recovery of Pleisto- cene mammalian fauna in the Shidu area in the far suburb of Beijing.The locality is located near the Xitaiping Village,20 km north of the Shidu Town (N39°45′02.3″,E115°34′44.5″). The cave occurred in the limestone of Precambrian age.The elevation of the entrance of the cave is 546 m.The fossil locality was recovered in 2005. AMS ~(14)C dating of mammalian bones gave the results:29 335～37 350 yrs BP.In chrono- logy,they are correlated with the Tianyuan Cave and Upper Cave Faunas at Zhoukoudian. More than a thousand pieces of fossils have been collected in Xitaiping Cave.The compo- nents of the fauna are as follows:Erinaceus sp.,Soriculus hypsibius,Rhinolophus ferrumequi- num,Eptesicus serotinus,Murina leucogaster,Lepus sp.,Ochotona sp.,Eutamias sibiricus, Pteromys volans,Aeretes melanopterus,Trogopterus xanthipes,Cricetulus barabensis,Rattus nor- vegicus,Microtus mandarinus,Vulpes vulpes,Arctonyx collaris,Mustela sp.,Mattes sp.,Sus scrofa,Moschus moschiferus,Cervus nippon and Pseudois nayaur.The dominant species are Moschus moschiferus,Pseudois nayaur and Aeretes melanopterus,It's a typical mountain fauna. All the taxa are extant ones.The Xitaiping Cave Fauna shares 76% species with the Late Pleis- tocene Fauna from Tianyuan Cave near Zhoukoudian (Choukoutien),and it also has 38% spe- cies in common with the Upper Cave Fauna at Zhoukoudian.In Xitaiping Cave Fauna,23% of the species have become locally extinct,most of which are medium and large mammals.The differences in compositions of the three contemporary faunas can be attributed to the difference in ecological environment. No reliable evidence of human activity has been detected in the cave,because there is nei- ther cut marks nor gnawing marks left on the bones.The cave deposits are composed of silt- gravel,and the gravels are fairly rounded.It indicates that the deposits were derived from water flows.
