Species
  • H. primigenius (von Meyer, 1829) (type species)
  • H. weihoense (Liu et al. 1978)
  • H. koenigswaldi (Sondaar, 1961)
  • H. catalaunicum (Perlot, 1956)

Hippotherium is an extinct genus of horse that lived in during the Miocene through Pliocene ~13.65—6.7 Mya, existing for 6.95 million years.

The last known surviving Hippotherium was H. malpassii, found in Italy.[1]

The type species, H. primigenium, is known from Miocene deposits in Europe (e.g., the Hegau region in southern Germany)[2] and the Middle East, while the species H. koenigswaldi and H. catalaunicum have been found in Miocene deposits in Spain.[citation needed] The Asian hipparionin "Hipparion" weihoense from early Late Miocene deposits in northern China has also been referred to the genus.[3]

Diet

[edit]

H. primigenium was a generalist feeder which frequently browsed but could also exploit grasses.[4]

Fossil distribution

[edit]
  • Doue-la-Fontaine France estimated age: ~13.65—7.25 Mya.
  • Lower Bakhtiari Formation, northern Iraq, estimated age: ~11.6—9.0 Mya.
  • Kurtchuk-Tchekmedje, Turkey estimated age: ~11.61—5.33 Mya.
