The common items found in Neolithic sites in Israel that reflect long distance trade are obsidian, greenstones and seashells. In the Pre-Pottery Neolithic B period such items are usually found in small quantaties in almost evey site. In Pottery Neolithic sites such items are very rare. Stekelis, from his excavations at Sha`ar Hagolan, did not mentioned any exotic raw materials. In the publication of the Munhata obsidian, no item was related to Layer 2b, but either to the Pre-Pottery Neolithic B layers or Layer 2a of the Wadi Rabah Culture(113).
In the new ecxavations at Sha`ar Hagolan one obsidian item was unearthed, and the ratio of flint to obsidian is 1:16071. In Munhata as well one obsidian item (bucket number 2687) which was related to Pre-Pottery Neolithic B layers(114) was unearthed in Pit 796 which contained classical Yarmukian pottery(115) and it is therefore a Yarmukian item.
