MURID RODENTS FROM THE LATE PLIOCENE OF YANGQUAN AND YUXIAN, HEBEI

Daodi is considered to be a late Pliocene locality near Nihewan, a classic site well known for its abundant and diverse Plio-Pleistocene mammalian fossils. An assemblage of micromammals was collected by the first author from eight quarries at Daodi by screen-washing in 1984. Preliminary reports on 26 species of small mammals collected and more detailed studies of lagomorphs have been given (see Cai, 1987; 1989). This paper deals with the material of the rodent family Muridae in the collections.
