Bithynia tentaculata (Linnaeus, 1758) as an indicator of age and deposition environment of Quaternary sediments. Folia Malacol
ABSTRACT: Shells and opercula of an aquatic snail Bithynia tentaculata (L.) occur commonly in Quaternary deposits as a substantial component of subfossil malacocenoses. They have been noted mainly in lacustrine chalk and calcareous gyttja, as well as in silts and muds accumulated in fluviatile envir...
