Miocene Perissodactyla

Chalicotherium (from Ancient Greek χάλιξ (khálix), meaning "gravel", and θηρίον (theríon), meaning "beast") is a genus of extinct perissodactyls in the family Chalicotheriidae. The genus is known from Europe and Asia, from the Early Miocene to Late Miocene, 23.0~5.3 million years ago.

Moropus (meaning "slow foot") is an extinct genus of large perissodactyl mammal in the chalicothere family. They were endemic to North America during the Miocene from ~20.4–13.6 Mya, existing for approximately . Moropus belonged to the schizotheriine subfamily of chalicotheres, and has the best fossil record of any member of this group; numbers of individuals, including complete skeletons, have been found. The type species of Moropus, M. distans, was named by Othniel Charles Marsh in 1877, alongside two other species, M. elatus and M. senex. Three more species have been named since. Others hav

Ancylotherium (from Greek, meaning "hooked beast") is an extinct genus of the family Chalicotheriidae, subfamily Schizotheriinae, endemic to Europe, Asia, and Africa during the Late Miocene-Early Pleistocene (11.6—1.8 mya), existing for approximately .

Parahippus ("near to horse"), is an extinct equid, a relative of modern horses, asses, and zebras. It lived from 24 to 17 million years ago, during the Miocene epoch. It was very similar to Miohippus, but slightly larger, at around tall, at the withers. Their fossils have been found in North America, primarily in the Great Plains region and Florida.

Megahippus is an extinct genus of large Anchitheriine horses found throughout the southern portion of the United States during the middle Miocene. The animal represents one of the latest low-crowned horses, overlapping in time with more derived high-crowned horses.

Dinohippus (from Ancient Greek δεινός (deinós), meaning "terrible", and ἵππος (híppos), meaning "horse") is an extinct equid which was endemic to North America from the late Hemphillian stage of the Miocene through the Zanclean stage of the Pliocene (10.3—3.6 mya) and in existence for approximately . Fossils are widespread throughout North America, being found at more than 30 sites from Florida to Alberta and from Mexico all the way down to Panama (Alajuela Formation). The majority of fossils of Dinohippus have been unearthed in the Western United States in Nevada, New Mexico, Utah, and Califo

Hypohippus (Greek: "under" (hypos), "horse" (hippos)) is an extinct genus of three-toed horse, which lived 17–11 million years ago. It was the largest anchitherine equid about the size of a modern domestic horse, at and long. It was a long-necked, high-shouldered browser with sub-hypsodont, lophodont (rhino-like) dentition, that fed on the tough vegetation of forest understory and shrubs. Its deep preorbital fossae and retraction of the nasal notch hint at the presence of a long, muscular and prehensile upper lip that would aid during selective browsing. Overall its ecology would have been mor

Protapirus (Latin: "before" (pro), + Brazilian Indian: "tapir" (tapira)) is an extinct genus of tapir known from the Oligocene and Miocene of North America and Eurasia.

Anisodon (from Ancient Greek ἄνῑσος (ánīsos), meaning "unequal", and ὀδούς (odoús), meaning "tooth", and thus, "unequal teeth") is an extinct genus of chalicothere that lived in Europe during the late Miocene. It stood at about and weighed around . It is thought that the animal's clawed forelimbs would have allowed it to pull down tree branches in order to browse, as well as deter Miocene predators such as bear-dogs and saber-toothed cats. thumb|left|Foot bones at the Gallery of Paleontology and Comparative Anatomy, Paris. thumb|left|Models in Basel

The genus is noted for several distinct skeletal features. The skull possesses deeply pocketed fossa in a notably long preorbital region. The genus is considered an example of phyletic dwarfism with adults estimated at being on average 20 kilograms in weight. This is in contrast to the most common equid of the period, Miohippus. Characters of the teeth show a mix of both primitive and advance

Hippotherium is an extinct genus of horse that lived during the Miocene through Pliocene ~13.65—6.7 Mya, existing for .

Nannippus is an extinct genus of three-toed horse endemic to North America during the Miocene through Pleistocene, about 13.3—1.8 million years ago (Mya), living around 11.5 million years. This ancient species of three-toed horse grew up to and weighed between 165 pounds (75 kilograms) to 199 pounds (90 kilograms), which was around the same size as a domestic sheep.

Kalimantsia is an extinct chalicothere from the Miocene of Bulgaria, Europe. It contains one species, Kalimantsia bulgarica.

Miotapirus harrisonensis is an extinct species of tapir lived during the early Miocene Epoch some 20 million years ago in North America.

Tylocephalonyx, from Ancient Greek (túlos), meaning "knob", (képhalos), meaning "head", and (ónux), meaning "claw/hoof", is an extinct schizotherine chalicothere from the Miocene of North America.

Desmatippus is an extinct, three-toed, browsing member of the Equidae. It lived in what is now North America during the Miocene period (about 23 mya to 5 mya). Desmatippus was 60 cm in height and 20 kg in weight.

Pseudhipparion is an extinct genus of three-toed horse endemic to North America during the early to late Miocene. They were herding animals whose diet consisted of C3 plants, implying that they were grazers. Fossils of Pseudhipparion have been found in Georgia, Florida, Oregon, Montana, Kansas, Texas, Nebraska, and South Dakota indicate that it was a lightweight horse, weighing up to 90 pounds (40 kilograms). In 2005, fossils were unearthed in Oklahoma. Seven species of Pseudhipparion are known from the fossil record, which were very small, following the trend of Bergmann's rule.

Plesiotapirus is an extinct genus of tapir from the Miocene of Asia. A single species is usually considered valid, Plesiotapirus yagii.
