Equus yunnanensis

The Yunnan horse, Equus yunnanensis, is an extinct species of equine that lived in East Asia during the Pleistocene, very likely as a grazer on open tracts of grassland. It was a small equine comparable in size to the modern Przewalski's horse. Edwin H. Colbert described it from dental fossils that Walter W. Granger collected in the Ma Kai Valley in northern Yunnan in the winter of 1926 to 1927, where it was the most numerous fossil of a single type of animal. Colbert thought it almost identical with an Equus from the Upper Irrawaddy sediments of Myanmar. Authors regard it as a stenonine horse, probably only distantly related to true horses and closer to zebras and asses.
