Equus yunnanensis, more commonly known as the Yunnan Horse, is an extinct horse that once roamed in Pleistocene East Asia very likely as a grazer on open tracts of grassland. It was a small horse comparable in size to the modern Przewalski Horse. Edwin H. Colbert thought it almost identical with an Equus collected by Teilhard de Chardin in the Upper Irrawaddy sediments of Burma: “Indeed, judging by the evidence at hand, these two representations of the genus, one in Burma and one in Yunnan appear to be cospecific”. There is also a horse breed called the Yannon.
