Cayonu, we can trace the succession of various levels. But we hardly see basic levels of developments such as housebuilding, agriculture and animal husbandry. The lowest layers dating (8800 - 8500 B.C.) testify to a permanently settled way of life on the basis of hunting and gathering. The next higher layer records the arrival of the first herd of sheep around 7300 B.C. (Cambel and Braidwood 1983).
Findings support the claims that wild pigs were firts domesticated in Cayonu, others wild sheep and wild goat.
The tools and other items produced non local materials, flint and obsidian, were found among the findings.
Surprisingly , findings revealed a class system in social life. There was a small group of people who possessed without working and a large group of people who worked without possessing.
Nevali Cori was located about 490 m elevation on both sides of the Kahta river, a minor tributary of Euphrates river.
Excavation works were conducted under the guidance of Professor Harald Hauptmann, University of Heidelberg during the construction of Attaturk Dam (1993) on the Euphrates. It is unfortunate that Nevali Cori with many other sites such as samsat(Samosata) have been inundated by the dammed waters of the Euphrates. T-shaped stone pillar found in the village had a human form with carved outlines of arms, elbows, hands, and fingers similar to those at Göbekli.
According to carbon dating, the earliest occupation of the site began around 8,400 BC. The settlement was continuously in use without interruption until the middle of the sixth millennium BC.
