摘要: 描述了产自甘肃省党河地区第三纪中期的跳鼠化石3 属7 种。其中5 种(Parasminthus asiaecentralis, P. tangingoli, P. parvulus, Heterosminthus lanzhouensis 和Litodonomys cf L . huangheensis) 产自狍牛泉组上部,时代为晚渐新世。产自早中新世( ?) 铁匠沟组中部的2 种是中间异蹶鼠(新种) (Heterosminthus intermedius sp. nov. ) 和西水简齿鼠(新种) (L

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.
