Dinohippus (Greek: "Terrible horse"[1]) 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 6.7 million years.[2][3] Fossils are widespread throughout North America, being found at more than 30 sites from Florida to Alberta and Panama (Alajuela Formation).
