摘要
甘肃灵台雷家河剖面产出的日进鼠化石包括了该属从老到新的所有种类 :中新世末—上新世初的C .primitivussp .nov.、早上新世的C .lingtaiensissp .nov .、早上新世—晚上新世初的C .yusheensis和早上新世—晚上新世的C .nihowanicus。系统描述了上述各种 ,对种间的演化过程及该属与Occitanomys和Orientalomys的关系进行了比较和讨论。
Totally 394 specimens of Chardinomys were collected from 3 sections which ranging from latest Miocene to early Pleistocene near Leijiahe Village, Lingtai County, Gansu Province by screen-washing during 1997～1999 field work seasons. These well stratigraphically calibrated specimens, representing all the forms known in China and 2 new primitive forms of this genus, give an unprecedented chance to revise all the known species and to study systematically the evolutionary relationships of the species in the genus. In addition, the relationships of Chardinomys with Occitanomys and Orientalomys are also discussed in this paper.
