The European wild ass (Equus hemionus hydruntinus) or hydruntine is an extinct equine from the Middle Pleistocene to Late Holocene of Western Eurasia. It appeared first in the fossil record around 350–300,000 years before present. In the late Pleistocene it was widespread throughout much of western Eurasia from the Middle East to Europe, especially along the Mediterranean, with fossil reports from Sicily, Turkey, Spain, France and Portugal. In the east the range apparently stretched at least to the Volga and to Iran. In the north it reached almost to the North Sea in Germany and the British Isles. Its range fragmented after the Last Glacial Maximum, surviving into the Holocene, its range gradually contracted further, persisting in small regions of southern Europe into the Bronze Age, and in Iran and the Caucasus into the Iron Age, around 500 BC. It has been suggested that the Iberian Zebro, extinct in the wild from the 16th century, could correspond to the Equus hydruntinus, although the word "zebro" or "cebro" comes from Latin equiferus meaning 'wild horse'. Later research judged that it was unlikely that hydruntines persisted in the Iberian Peninsula beyond the Chalcolithic.
