Equus occidentalis(commonly known as thewestern horse) is an extinctspeciesofwild horsethat once inhabitedNorth America,specifically theSouthwestern United States,during thePleistoceneepoch.^[1]^[2]^[3]^[4]It was first described from three teeth with insufficient diagnostic characters, one even being suggested to be a separate taxon related to theAmerican Zebra,leading some researchers to consider it anomen dubium,though this taxonomic debate is yet to be fully resolved.^[5]^[6]

E. occidentaliswas about the same size as the modernArabian horse,measuring up to 1.47 metres (4.8 ft) in shoulder height. It was morphologically and proportionally similar to the modern dayzebra.^[7]
