Skeleton of the extinct Western Horse (Equus occidentalus), George C. Page Museum at the La Brea Tar Pits, Los Angeles, California.
Due to the fragmentary nature of the fossils of this species found so far, it has been difficult to reconstruct how the head and the rest of this horse's body might have looked. This is the equus occidentalus.

Interestingly, modern North American Horses are not direct descendants of the ancient varieties. All American wild horse species died off about 12,000 years ago during the great American extinction.
