Opis:: A profile of loess several metres thick with palaeosoils, underlain by calcareous gyttja, out crops in Kolodiiv, Ukraine. Rich and diverse assemblages of molluscs have been found in these deposits. Three types of mollusc communities can be distinguished. The oldest is dominated by freshwater taxa and corresponds to calcareous gyttja of Eemian age. The next two assemblages contain only snails typical of loess. The first of these indicates a cold and dry climate and open environment of arctic steppe type, with rapid accumulation of loess; the second assemblage represents a cold and humid climate and a relatively moist, open environment of tundra type.

They form fill ings of palaeolakes which de vel oped dur ing the deglaciation. These for ma tions are usu ally cov ered by peat. Rich and di ver si fied malacofauna has been found in the afore men tioned sed i -ments. The pro files from 154 sites de scribed and pub lished by var i ous au thors were sub jected to malacological anal y -sis. In the whole ma te rial, 18 mol lus can as sem blages were dis tin guished, rep re sent ing three types of hab i tats: terrestrial,of tem po rary wa ter bod ies, and of per ma nent wa ter bod ies.
