Potsherds from a few vessels with Cardium decoration were recently found in old collections of some Neolithic sites of the Northern Black Sea area. A good samples of the valves of brackish water ostracods were discovered in the raw material in most of these vessels. This could indirectly indicate the presence of Neolithic settlements with Cardium pottery on what is now a flooded region of the northern Black Sea coast. Some data show that its inhabitants could have been the initial source of the Neolithisation of neighbouring inland territories. Thus, the whole local Neolithic in the region is interpreted as a northeastern branch of the Mediterranean Neolithic with Impresso and Cardium pottery.
