Recent fieldwork in the main excavation area at Göbekli Tepe has focused on the excavation of deep soundings to reach the natural bedrock in preparation for the construction of a shelter, urgently required for the protection of the exposed Neolithic architecture. Eleven deep soundings have been excavated to the bedrock. At several locations, considerable amounts of carbonized botanical material were discovered, so far unique for excavations at Göbekli. A series of more than 150 samples has been produced either on site or by flotation of the relevant soil units. To test the quality of the material for radiocarbon dating, five samples from the area of the large enclosures from Layer III were submitted for AMS-radiocarbon dating. These new data, together with a further age made on collagen from an animal tooth, are presented and discussed in context with previously available absolute chronological evidence.”
