Very interesting. According to Ryan and Pitman, the
Bosphorus straight broke thru to the Euxine lake about 5500 BC as you well know. The preliminary dating of this new site is 5,000 BC. If I remember correctly, about this time the ocean level were about 1 meter higher than now. So this site should be underwater during the time it was flourishing. This means there has been major subsidence in the area or the sea level was fluctuating widely in small geographic areas.
