ABSTRACT - The discovery of a new hipparionine metacarpal III in 2010 has led to the recognition of the occurrence of the East African species Eurygnathohippus feibeli at Sahabi. Specimens of metacarpal III and metatarsal III previously referred to cf. Hipparion s.s. are reassigned herein to Eurygnathohippus feibeli. The occurrence of an East African hipparionine horse at Sahabi is congruent with findings of other Late Miocene ungulates and strengthens the biogeographic connections between the Sahabi and the Ethiopian Middle Awash and Kenyan Lothagam faunas. Taking into consideration the known biogeographic connections to eastern Mediterranean - Southwest Asia faunas, the Sahabi findings constitute a crucial crossroads fauna between Eurasia and Africa and reflect the maximum extension of Old World Pikermian faunas in the Late Miocene.
