    Malakofauna późnoglacjalnych i holoceńskich węglanowych osadów jeziornych północnej Polski
    (Wydawnictwa AGH, 2007) Alexandrowicz, Witold Paweł
    Late Glacial and Holocene mollusc-bearing deposits developed as lacustrine chalk and/or calcareous gyttja are widespread in Northern Poland. They fill up water bodies formed during the final stage of deglaciation. These sediments usually contains rich assemblages of molluscs. Calcareous lake deposits and it's malacofauna were described in detail by several authors in 54 localities. Eighteen communities of snails and bivalves have been distinguished. They are represents three types of environment: land, temporary water bodies and permanent water bodies (lakes). The composition and structure of malacocenoses reflect changes of the climate and differentiation of habitats. Three types of malacological sequences can be define. The scheme of evolution water bodies during the Late Glacial and Holocene in Northern Poland was elaborated based on successions of molluscan communities.
