Abstract

The species-rich fossil vertebrate assemblage from Pleistocene sedimentary deposits at Kisláng, Hungary, was originally described as containing eight species of arvicolids, six of which were considered new. Re-examination of the material in the collection of the Hungarian Geological Institute, consisting of most of the previously described material, including the six name-bearing types and also further undescribed specimens, indicates that the taxa Kislangia rex, Mimomys cf. hassiacus, Mimomys coelodus, Mimomys pusillus, Mimomys tornensis, Pitymimomys sp., Borsodia newtoni, Lagurodon arankae and Allophaiomys deucalion are present. Most of these species are compatible with Early Pleistocene age close to the boundary between the Villányian and Biharian regional stages (MQR10, MQ1, c. 1.6–2.0 Ma). However, the specimen of Mimomys cf. hassiacus is of approximately mid-Pliocene age (MN15 c. 3.6–4.0 Ma), and one of the Pitymimomys specimens is referable to P. stenokorys, described from the earliest Pleistocene (MNR2–MNR3, MN17 c. 2.3–2.4 Ma). The assemblage is therefore interpreted as derived from at least three different geological periods and because of reworking of material is considered unusable to characterize any particular stratigraphic level. These conclusions are placed in the context of historical and current biostratigraphies.
