Abstract: The Niutoushan (or Pulu) section, which was originally described by Du et al.(1988) as one of the stratotypes in erecting the"Daodi Formation", is located about one kilometer south of Pulu village, Yuxian county, and 1.2 km north of the Danangou section(Cai et al.,2004). Both the Niutoushan and the Danangou sections are on the east side of the highway connecting Xuanhua city to the Yuxian county seat.In addition to the Donggou section near the Qianjiashawa village, the Niutoushan section potentially represents the only other record of the Pliocene/Pleistocene boundary in the Nihewan district, as indicated by the presence of derived Mimomys cf.M. youhenicus. We remeasured the Niutoushan section to develop a more complete profile in 2005. The profile was original 43.18 m measured by Du et al.(1988). As a result of our fieldwork, the profile is now 82 m, with an additional 12 stratigraphic layers (11 to 23)(see Fig.1). Small mammals were collected from Layers 3,6,9,12,15 and 16 by screen-washing(see Table 1). The mammals from each layer represent one faunal complex with some species spanning multiple layers.
