Paleontology and Stratigraphy of Fossils

Detailed studies of trace fossils have been carried out in five sections of glaciolacustrine varved sediments (Balbieriškis 2 and 3 outcrops, clay pits of Pašaminė, Krūna and Tauragė).Trace fossils gor dia isp., Helminthoidichnites isp.and galaciichnium liebegastensis are relatively common, and Coch lichnus anguineus, Warvichnium ulbrichi and curved ridges are rare.These trace fossils are typical of the Mermia ichnofacies.Their occurrence is related to the warmer climate of the Late Pleistocene North European glacial interphasials or interoscillations.The trace fossils can be used for recognition of lacustrine subfacies and climatic warming.
