Abstract

The small fossils (Rodentia and Eulipotyphla) from Csönget-Völgy near Vértesacsa in Western Hungary are presented herein; and although the assemblage contains relatively poor material, we describe nine rodent taxa and two insectivore species. The rodents are Apodemus lugdunensis, Kowalskia cf. polgardiensis, Anomalospalax cf. tardosi, Lophocricetus cf. cimishliensis, Keramidomys ermannorum, Eomyops sp., Muscardinus sp., Spermophilinus sp., and fragmentary beaver remains.Insectivores include Petenyia hungarica and Asoriculus gibberodon. Correlation with Turolian, late Miocene is proposed basedon rodent assemblage. A minor overlap of presented biostratigraphic age with authigenic ¹⁰Be/⁹Be ages obtained from the same locality is discussed. This locality adds important information to our knowledge of deposits and chronology of the late Miocene Zagyva Formation.

Key words: Transdanubian Range, late Miocene, Turolian, stratigraphy, Mammalia, cosmogenic nuclide.
