This chapter discusses the hipparionine horses of the Eurygnathohippus clade from the Middle Awash late Miocene. It presents the morphological description and statistical analysis of the Middle Awash hipparions ranging in age from 6.0 to 5.2 Ma. It examines two taxa of Middle Awash late Miocene hipparion, Eurygnathohippus feibeli, from the oldest stratigraphic levels of Jara-Borkana and an apparently slowly evolving derivative, Eurygnathohippus aff. feibeli, from the 5.7 to 5.2 Ma interval. The chapter describes the discrete morphology of skull fragments, mandibular remains, and maxillary and mandibular dentitions by stratigraphic level and locality for each of the recognized taxa.
