Abstract: Since the Cenozoic, changes of mammals in taxonomic composition and distribution have taken place in China, mainly due to collision of plates, changes of topography and climate. The paper discusses some problems of ecology and biogeography involving the Chinese Cenozoic mammals, after the recognition of the 18 mammal ages based on nature and magnitude of the faunal changes (Tong et al., 1995).
