Abstract: The fossil dipodids of the Danghe area, Gansu, were described by Bohlin (1946), allegedly from a single late Oligocene level. Due to the extremely complex tectonic disturbance of the strata in the study area, Bohlin’s age determination needs to be verified stratigraphically. In 1999 and 2001 a joint team of Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences (IVPP), Cultural Relic Archaeology Institute of Gansu and Gansu Province Museum made a geologic survey of the Danghe area. As a result, a number of stratigraphic problems were clarified and some new mammalian fossils were collected from stratigraphically known levels (Wang et al., 2003). Among the fossils the dipodids are one of the most abundant, including not only the taxa described by Bohlin (1946), but also 2 new species from new levels.
