| Abstract:This paper describes in brief some Middle Jurassic mammals from the eastern part of northern China,which include Liaotherium gracile,Castrocauda lutrasimilis,Volaticotherium antiquus and Pseudotribos robustus.Liaotherium gracile was found in the Jiulongshan Formation of Fangshen village,Lingyuan City,Liaoning Province,and the other three kinds were all unearthed from the Tiaojishan Formation in Daohugou area,Ningcheng County,Inner Mongolia.The discovery of these fossil mammals has not only enriched the components of Middle Jurassic biota in China and deepened our understanding of the diversity of mammals in Middle Jurassic,but also provided the palaeontological evidence for the subdivision and correlation of Late Mesozoic strata in the eastern part of northern China. |
