| Abstract: | The Middle Pleistocene Caryomys from Zhangping caves,Luonan County,Shaanxi Province is described into two extant species,C.eva and C.inez,that only live in North China.C. eva is characterized by 5 lingual and 4 buccal salient angles on m1 and by 3 lingual and 3 buccal salient angles on M3.C.inez is slightly more complicated than C.eva because its m1 has 6 lingual salient angles and its M3 has an elongated posterior loop with the fourth lingual salient angle sometimes.It is different from C.regulus living in... |
