Meso hippus
Mesophipus is one of the extinct horses belonging to the milk culture that survived from the early Miocene to the early Miocene, about 40 to 28 million years ago. It was first discovered in 1875 in the Badlands region of South Dakota. Fossils have been found in many parts of the United States, including North America, Nebraska, Iowa, Wyoming, and California. It has a nearly perfect form of horses, and has a brain that is similar in size to the current horse and donkey. The fossil is the first horse with three toes. The meso hippus found in the early and middle layers of the Oligocene in North America was comparatively small in size and comparable in size to today's dog, but the appearance was quite similar to today's horse. The height up to the shoulder is 60cm, which is much closer to Hyogo than Eohefus or Orohitsu who lived in Eoise. Mesophipus became more leggy, thinner, and bigger as the generation descended. His neck became pliant, his eyes wide, and he could look back.
