Mansancun Micromammal Fauna from the upper part of the Jiaozigou Formation in Linxia Basin,Gansu Province
摘要
Abstract
The micromammal fossils collected from the upper part of the Jiaozigou Formation near Mansancun in 2015 are described.The sample consists of 10 species of six previously known genera(Amphechinus,Sinolagomys,Parasminthus,Litodonomys,Heterosminthus and Yindirtemys)belonging to three orders.Of them,four genera(Sinolagomys,Litodonomys,Heterosminthus and Yindirtemys)made their first appearance in the Late Oligocene and Sinolagomys kansuensis and Heterosminthus lanzhouensis are known only in the Late Oligocene.In comparison with the other Late Oligocene mammalian faunas known in China and Mongolia,the above assemblage appears to be contemporaneous with Xiagou,Taben-buluk,Yikebulage faunas and Tieersihabahe assemblages,but slightly younger than the Shargaltein-Tal Fauna in age.The Mansancun Fauna is also younger than the three Late Oligocene biozones recognized recently in Asia.Compared with the Yagou Fauna collected from the lower part of the Jiaozigou Formation,the Mansancun Local Fauna is clearly younger.Consequently,the Yagou Fauna would be early Late Oligocene,while the Mansancun Local Fauna may be considered late Late Oligocene.Thus,as a whole,the Jiaozigou Formation is Late Oligocene in age.关键词
