An Upper Palaeolithic flint industry following the Mousterian in northern Iraq and Iran, with the type site in a cave at Shanidar. It has radiocarbon dates c 30,000 BC and may have begun as early as 36,000 BC. The Baradostian was replaced by a local Upper Palaeolithic industry called the Zarzian (12,000-10,000 BC), probably caused by the extreme cold of the last phase of the Würm glaciation. The Zarzian marks the end of the Iranian Paleolithic sequence that preceded various Mesolithic developments in the Middle East.
