Eurygnathohippus is an extinct genus of hipparionine horse.[2][1] The majority of known fossils of members of this genus were discovered in Africa, where members of this genus lived during the late Miocene to Pleistocene interval.[1][3] Fossils of Eurygnathohippus were also reported from the late Pliocene sediments of the Potwar Plateau in Pakistan and the Siwalik Hills in northwest India.[4]
Palaeobiology
Life history
The osteohistology of E. hooijeri from Langebaanweg suggests that it had a slow life history, with its ages of weaning, skeletal maturity, and reproductive maturity being reached relatively late when compared to extant members of Equus and to three-toed equids in Europe. Adults of the species had low extrinsic mortality, but juveniles would have experienced high mortality rates.[5]
