摘　　要：Yanjinggou in Wanzhou District of Chongqing is one of the earliest reported and most famous Quaternary mammalian fossil areas in China.The fauna from this area used to be taken as a benchmark for the biochronological comparison of Quaternary paleontology of South China,but the chronology of this fauna has many controversies for the lack of exact locational and stratigraphical records.The present article,on the basis of recent investigations and discoveries,discusses and explains the distribution and biochronology of the mammalian faunas in the Yanjinggou area.The newly discovered Dayakou fissure fauna,including Rhizomys troglodytes,Homotherium sp.,Panthera pardus,Stegodon orientalis,Dicerorhinus sumatrensis,Hesperotherium sinense,Sus sp.,Cervavitus fenqii,Cervus sp.and Muntiacus sp.,is correlated to the middle Early Pleistocene.The presence of Early Pleistocene mammalian fauna in the Yanjinggou area is therefore confirmed.The"Wanhsien fauna"or"Yenchingkou(=Yanjinggou)fauna"as a Mid-Late Pleistocene biostratigraphical datum should be abandoned.The Dayakou fauna and the Upper Cave fauna of Pingba,both in the Yanjinggou area,are correlated to the middle Early Pleistocene and the early Middle Pleistocene in age,respectively.Yanjinggou in Wanzhou District of Chongqing is one of the earliest reported and most famous Quaternary mammalian fossil areas in China.

The present article, on the basis of recent investigations and discoveries, discusses and explains the distribution and bio- chronology of the mammalian faunas in the Yanjinggou area. The newly discovered Dayakou fissure fauna, including Rhizomys troglodytes, Homotherium sp., Panthera pardus, Stegodon orientalis, Dicerorhinus sumatrensis, Hesperotherium sinense, Sus sp., Cervavitusfenqii, Cervus sp. and Muntiacus sp., is correlated to the middle Early Pleistocene. The presence of Early Pleistocene mammalian fauna in the Yanjinggou area is therefore confirmed. The ＂Wanhsien fauna＂ or ＂Yenchingkou （=Yanjinggou） fauna＂ as a Mid-Late Pleistocene biostratigraphical datum should be abandoned. The Dayakou fauna and the Upper Cave fauna of Pingba, both in the Yanjinggou area, are correlated to the middle Early Pleistocene and the early Middle Pleistocene in age, respectively.
