This region is also the location of a number of pre-Neolithic burials, dating from approximately 11,000 BC.Ralph S. Solecki, Rose L. Solecki, and Anagnostis P. Agelarakis (2004). The Proto-Neolithic Cemetery in Shanidar Cave. Texas A&M University Press. pp. 3–5. . Since approximately 10,000 BC, Iraq, together with a large part of the Fertile Crescent, was a center of a Neolithic culture known as Pre-Pottery Neolithic A (PPNA), where agriculture and cattle breeding appeared for the first time. In Iraq, this period has been excavated at sites like M'lefaat and Nemrik 9. The following Neolithic period, PPNB, is represented by rectangular houses. At the time of the pre-pottery Neolithic, people used vessels made of stone, gypsum, and burnt lime (Vaisselle blanche). Finds of obsidian tools from Anatolia are evidence of early trade relations. Further important sites of human advancement were Jarmo (circa 7100 BC), a number of sites belonging to the Halaf culture, and Tell al-'Ubaid, the type site of the Ubaid period (between 6500 BC and 3800 BC).Carter, Robert A. and Philip, Graham Beyond the Ubaid: Transformation and Integration in the Late Prehistoric Societies of the Middle East (Studies in Ancient Oriental Civilization, Number 63) The Oriental Institute of the University of Chicago (2010) p.2, at http://oi.uchicago.edu/research/pubs/catalog/saoc/saoc63.html ; "Radiometric data suggest that the whole Southern Mesopotamian Ubaid period, including Ubaid 0 and 5, is of immense duration, spanning nearly three millennia from about 6500 to 3800 B.C".
