Abstract: The paleontologists of IVPP about ten times from 1992 to 1999 and together with colleagues from the Carnegie Museum of Natural History in Pittsburgh from 1994 to 1997 had made successful investigation in Yuanqu Basin, Central China, resulting in finding a great deal of fine fossils, including Primates, Rodentia and Insectivora. The specimens of Perissodactyla are not well preserved and most of them are isolated teeth. But these fossils not only increase new material of certain old groups (Deperetella depereti, Prohyracodon meridionale, Caenolophus promissus, Sianodon mienchiensis and Sianodon sinensis) but also add some taxa that have been found for the first time in the Basin (Rhodopagus yunnqnensis, Breviodon sp. and Teleolophus cf. T. Mangshanensis). These fossils were found in two localities: Hedi, Yuanqu County, Shanxi Province and Rencun, Mienchi County, Henan Province. The fossil—bearing beds belong to Rencun Member, Hedi Formation of the Middle Eocene.
