In appearance, the diadiaphoruses strongly resembled horses and notogippyds , however, the body length was only 1.2 m, as in a modern sheep. There were three fingers on the limbs, of which only one touched the ground. This finger was equipped with a large hoof evolving from the claw; the two outer fingers were rudimentary, like early equine fingers (such as the merikippus ). Unlike horses, diadiaphoruses did not have fused limb bones.
The skull was short, but the cavity for the brain was quite large. Judging by the lower molars, the diadiaphorus fed on soft plant foods, for example, leaves [2] .
