2008 m. Nr. 4 Holocene malacofauna in calcareous deposits of Dūkšta site near Maišiagala in Lithuania
The paper contains results of new investigations in Lithuania of the first occurrences of terrestrial molluscs in calcareous tufa (travertine), carbonate content and radiocarbon dating. Terrestrial fossil molluscs (35 taxa) prevail in the mollusc fauna, while freshwater species are much more rare (6 taxa). The Dūkšta terrestrial mollusc fauna embraces a complex of thermophiles including such forest species as Acicula polita (Hartmann), Acanthinula aculeatа (Müller), Aegopinella cf. pura (Alder), Bulgaria сапа (Held) and Discus cf. rotundatus (Müller), as well as mainly South European Carychium tridentatum (Risso) and mainly West European Vertigo moulinsiana (Dupuy). The radiocarbon age of the
sediments was found to correspond to the end of the Atlantic climatic period and the beginning of the Subboreal. Keywords: malacofauna, calcareous deposits, radiocarbon age, Holocene, Lithuania |
