Magyar Őslénytani Vándorgyűlés (Budapest), Abstract, Magyarhoni Földtani Társulat, Budapest, 38. 2007 The Results of the Paleontological Investigation at the Sand Mine near Szirák (Hungary) by Attila Virág & Endre Krolopp Middle Miocene marine remains (foraminifers, molluscs and crustaceans), Late Pleistocene freshwater and terrestrial molluscs and Late Pleistocene vertebrates were found at the sand mine near Szirák (North East Hungary). The age of the locality was determined on the basis of biostratigraphic considerations. The Pleistocene mollusc assemblage belongs to the Helicigona banatica - Phenacolimax annularis biozone, which can be correlated with the Stit- tőien and Varbóian substage of the local biochronological system. The dominance of Arvicolidae with the co-occurrence of Microtus arvalis and Arvicola terrestris, as well as the absence of arctic species (e.g. Dicrostonyx) or the infrequency of small predatory mammals in the vertebrate fauna suggest a latest Süttőien or an earliest Varbóian age. The occurrence of Sorex species and Myodes glareolus are more characteristic for the latter. The Badenian and Sarmatian remains were mixed into the fauna when a low- energy stream redeposited some Miocene sediments during the Riss-Würm interglacial stage. The remains were transported only a short distance from the source region, thus the Late Pleistocene fossils could provide some information about the ecology of the surrounding area. Mild but slightly more humid climate and closed or semi-closed forested vegetation can be reconstructed on the basis of the remains. 252
