History of the horse in the Indian subcontinent "The occurrence of true horse ("Equus caballus" L.) was evidenced by the enamel pattern of the upper and lower cheek and teeth and by the size and form of incisors and phalanges (toe bones).". However, archaeologists like Meadow (1997) disagree, on the grounds that the remains of the "Equus ferus caballus" horse are difficult to distinguish from other equid species such as "Equus asinus" (donkeys) or "Equus hemionus" (onagers).

Equus niobrarensis Equus niobrarensis Equus niobrarensis (or commonly, Niobrara horse) is an extinct species of "Equus", the genus that includes the horse.

The skull of the horse was noted as being broader than Equus caballus. "E. niobrarensis" was native to North America and commonly found in western North America and dates to the late Pleistocene. Fossils of "E. niobrarensis" were discovered at Dry Cave in Wisconsin. Another mention of an "E. niobrarensis" discovery was in Skeleton Cave, Oregon.
