Medistylus is an extinct genus of pachyrukhine hegetotheriid. It lived in Argentina during the Late Oligocene. Medistylus is known from its upper teeth and isolated skulls, however, its lower dentition is currently unknown. Its fossilized remains were found at the Cabeza Blanca and Las Cascadas localities of the Sarmiento Formation in Chubut Province of Argentina.[1]
