Sediments, carbon-datings on seashells, allow us to reconstruct the evolution of the average sea level for some 6000 years on the Taman Peninsula. The current sea level, regionally, appears to be the highest level ever reached on the peninsula. It seems that for the Anapa area and Tchouchtchka Spit area it is possible to propose a sea level curve characterised by a slow, continuous rising during the past 6000 years. On the Taman Peninsula itself, the sedimentary record of this slow ascent has been distorted by a heavy tectonic subsidence. We have identified this neo-tectonic subsidence effect on at least two areas on the peninsula. The south of the peninsula, Burgaz Spit and Vityazevos Lagoon, is the most affected area. The Taman Gulf is an intermediate area. The tectonic subsidence is particularly noticeable from 1500 to 500 BC, which we believe to have been misinterpreted until now, and to be at the origin of the notion of "Phanagorian Regression".
