Diadiaphorus

Diadiaphorus is an extinct animal that is known for its resemblance to a horse, but much smaller in size and with three toes on each foot.
It lived in South America during the Miocene epoch, about 17.5 to 6.8 million years ago.
It was a herbivore that ate soft plants, such as leaves.
It had a short skull and a relatively large brain.
It belonged to the order of litopterns, which were mammals that evolved independently from other hoofed animals.

Diadiaphorus was a genus of extinct mammals that belonged to the order Litopterna, which were native to South America.

They lived in the Miocene epoch, about 17.5 to 6.8 million years ago.

Diadiaphorus looked similar to a horse, but was much smaller, only about 1.2 meters long and 70 kilograms in weight.

It had three toes on each foot, but only the middle one touched the ground and had a large hoof.

Unlike horses, however, Diadiaphorus did not have fused bones in its limbs.

Its skull was short and had a relatively large brain cavity.

It probably ate soft plants, such as leaves, as indicated by its low-crowned molars.

Diadiaphorus was one of the many diverse and unique mammals that evolved in isolation in South America, before the continent was connected to North America by the Isthmus of Panama.
