The Chinese fossils of Equus began to appear from the beginning of the Quaternary at 2.5 Ma B.P., and the extant species of Eqtms still live in China under natural conditions at the present, which is unique in the world. 12 valid fossil species of Equus have been discovered in China, including the stenonid, caballoid and hemione representatives of Equus. The origin and evolution of the Chinese fossil species and other relevant species of Eqnus are discussed in detail. The proposed phylogenetic relationships and temporal distribution sequences including all the Chinese fossil species of Equus are established. Some mistakes in the earlier researches about the Chinese fossils of Equus are corrected.
