ABSTRACT - The Pliocene fossil record of hipparionine horses in the Indian Subcontinent is poorly known. Historically, only one species, “Hippotherium” antelopinum Falconer & Cautley, 1849, was described from the Upper Siwaliks. Here, we present the frst evidence of Eurygnathohippus Van Hoepen, 1930, a lineage hitherto only known from Africa, in the Upper Siwaliks during the late Pliocene. Morphologically, the South Asian Eurygnathohippus is most similar to Eurygnathohippus hasumense (Eisenmann, 1983) from Afar, Ethiopia, a species with a similar temporal range.
