Göbekli Tepe time period Neolithic
Background
Göbekli Tepe was built and occupied during the earliest part of the Southwest Asian Neolithic, known as the  Pre-Pottery Neolithic (PPN, c. 9600–7000 BCE). Beginning at the end of the last Ice Age, the PPN marks "the beginnings of village life", producing the earliest evidence for permanent human settlements in the world. Archaeologists have long associated the appearance of these settlements with the Neolithic Revolution—the transition from hunting and gathering to agriculture—but disagree on whether the adoption of farming caused people to settle down, or settling down caused people to adopt farming. Despite the name, the Neolithic Revolution in Southwest Asia was "drawn out and locally variable". Elements of village life appeared as early as 10,000 years before the Neolithic in places, and the transition to agriculture took thousands of years, with different paces and trajectories in different regions. Archaeologists divide the Pre-Pottery Neolithic into two subperiods: the Pre-Pottery Neolithic A (PPNA, c. 9600–8800 BCE) and the Pre-Pottery Neolithic B (PPNB, c. 8800 and 7000 BCE). The earliest phases at Göbekli Tepe have been dated to the PPNA; later phases to the PPNB.Evidence indicates that the inhabitants of Göbekli Tepe were hunter-gatherers who supplemented their diet with early forms of domesticated cereal and lived in villages for at least part of the year. Tools such as grinding stones and mortars and pestles found at the site have been analyzed and suggest considerable cereal processing. Archaeozoological evidence hints at "large-scale hunting of gazelle between midsummer and autumn."Layer II
The creation of the circular enclosures in layer III later gave way to the construction of small rectangular rooms in layer II. Rectangular buildings make more efficient use of space compared with circular structures. They often are associated with the emergence of the Neolithic, but the T-shaped pillars, the main feature of the older enclosures, also are present here, indicating that the buildings of Layer II continued to serve the same function in the culture, presumably as sanctuaries. Layer II is assigned to Pre-Pottery Neolithic B (PPNB). The several adjoining rectangular, doorless, and windowless rooms have floors of polished lime reminiscent of Roman terrazzo floors. Carbon dating has yielded dates between 8800 and 8000 BCE. Several T-pillars up to 1.5 meters tall occupy the center of the rooms. A pair decorated with fierce-looking lions is the rationale for the name "lion pillar building" by which their enclosure is known.A stone pillar resembling totem pole designs was discovered at Göbekli Tepe, Layer II in 2010. It is 1.92 metres high and is superficially reminiscent of the totem poles in North America. The pole features three figures, the uppermost depicting a predator, probably a bear, and below it a human-like shape. Because the statue is damaged, the interpretation is not entirely clear. Fragments of a similar pole also were discovered about 20 years ago in another site in Turkey at Nevalı Çori. Also, an older layer at Göbekli features some related sculptures portraying animals on human heads.
