2007 m. Nr. 4 The first finding of Belgrandia marginata (Michaud) among the Quaternary molluscs in Lithuania
An Atlantic mollusc Belgrandia marginata (Michaud) has been detected for the first time in Lithuania among the Netiesos interglacial fauna (southeastern Lithuania). Considering that this species in Poland, Belarus and Lithuanian occurs only in the malacofauna of the last (Eemian) interglacial, it is stratigraphically significant in the indicated region. The malacological investigations of the Netiesos interglacial deposits revealed the mollusc fauna richer than had been found earlier in the Merkinė interglacial fauna. Moreover, the lower part of the deposits in the section studied contained shells of periglacial molluscs, such as Columella columella (Martens), Vallonia tenuilabris (A. Braun) and Vertigo genesii (Gredler), which correspond to the late glacial stage of the penultimate (Medininkai or Pripyat) glaciation.
