A set Archaic anchor arm exposed within P-oceanica matte at Klazomenai/Liman Tepe, Turkey: A contribution for understanding marine stratigraphy

Excavation in Posidonia oceanica matte in the ancient harbor of Klazomenai/Liman Tepe, on the Aegean coast of Turkey, demonstrates the stratigraphic archaeological potential of underwater excavation. Among the finds is a fractured wooden anchor arm exposed in situ. The anchor arm dates to approximately 600 B.C. based on stratigraphically associated ceramics, a dating supported by radiocarbon. The arm was found embedded in this marine sediment, which preserved the arm in its set position within the ancient sea floor. This archaeological excavation through matte and silt harbor sediments overturns the misconception that stratigraphic excavation is impossible in a marine environment. The excavation further boosts optimism regarding the preservation of maritime heritage along the littoral of the eastern Aegean and the many other Mediterranean regions where Posidonia oceanica grows.
