What is another word for protohippus?
Pronunciation: [pɹˈə͡ʊtə͡ʊhˌɪpəs] (IPA) 
Protohippus, a genus of extinct horses that lived during the Miocene epoch, is also known by several other names. The genus was previously classified as "Pliohippus" by some paleontologists, while others referred to it as "Hypohippus" or "Merychippus." Protohippus was a small horse, with a height of approximately 12 hands and a weight of around 400 pounds. Its fossils have been found in parts of North America, particularly in the Western United States. Protohippus is believed to have had three toes on each foot, similar to modern horses, but with slightly longer legs and a more robust body.
