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