[2] According to the Florida Museum of Natural History, Othniel Charles Marsh first believed Miohippus lived during the Miocene and thus named the genus using this incorrect conclusion.

[citation needed] Miohippus was larger than Mesohippus and had a slightly longer skull.

Miohippus also had a variable extra crest on its upper molars, which gave it a larger surface area for chewing tougher forage.

The Kalobatippus managed to relocate to Asia via the Bering Strait land bridge, and from there moved into Europe, where its fossils were formerly described under the name Anchitherium.

Kalobatippus is then believed to have evolved into a form known as Hypohippus, which became extinct near the beginning of the Pliocene.
