Up to now, two areas of northern and west-central Zagros Mountains (ZM) have produced better information concerning the development of techno-typology of lithic artefacts during the Epipaleolithic period (EP) compare to the other part of this region. Although several caves and rockshelters associated with EP deposits are found in this region (Map 1), but they were not subject to study for the relationship between climate effect on cultural developments like the neighbored area of Levant. this deficiency can be attributed to a) the low number of excavated sites, b) poor stratigraphic control, and c) the lack of a sufficient number of absolute dates. Recent absolute date achievements from the EP site of Palegawra cave [17]. locates on the northern ZM alongside Paleoclimatic reconstruction in Hashilan wetland [8] based on the palynological studies have improved our understanding from Epipaleolthic cultural and environmental events for the region.
