| 摘要 | The Lower Pliocene of the Linxia Basin in Gansu Province is one of only a few representative sections for the Early Pliocene sedimentary records in northern China,and even in East Asia.Recently,abundant mammalian fossils were found from the base of red clays of the Lower Pliocene Hewangjia Formation at Duikang in Guanghe County within this basin.Previously,the Pliocene mammals were sparsely found in China,and most were collected from fluvial and lacustrine deposits in the eastern Loess Plateau.Mammals from the widely distributed Pliocene Hipparion Red Clay are less in number.The known fossils from Duikang include 20 species and belong to the Shilidun Fauna.Their faunal components are similar to the Early Pliocene Gaozhuang Fauna from Yushe,Shanxi.On the other hand,some taxa from Duikang have not been found in the Gaozhuang Fauna,are slightly more primitive in evolutionary level,and appeared mainly in the Late Miocene.As a result,the age of the Duikang fossils may be slightly earlier than that of the Gaozhuang Fauna and closer to the lower boundary of the Pliocene.The Duikang fossiliferous bed is 0.8 m above the top of the Late Miocene Liushu Formation,and the first occurrence of the three-toed horse Hipparion pater can be regarded as a biostratigraphical marker of the Miocene/Pliocene boundary.In conclusion,Duikang is an ideal candidate locality to establish as the stratotype of the lower boundary of the Chinese terrestrial Pliocene. |
