The rhinocerotid fossils from the Lufengpithecus site in Lufeng, Yunnan, were collected during the period from 1975 to 1983. They were preliminarily identified as Aceratherium sp. nov. and Chilotherium sp. nov.(Qi,1979,1985). A further study of these fossils indicates that they represent a new species of Acerorhinus and a species of Shansirhinus, respectively. In this paper, terminology of rhinocerotid teeth mainly follows Antoine, and that of lower teeth is according to Qiu and Wang. IVPP Loc. and IVPP V are the locality and specimen prefixes of Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, respectively.
