FRAGMENTA MINERALOGICA ET PALAEONTOLOGICA 18. BUDAPEST, 1996 p. 79-90 Cricetinus janossyi sp. n. (Rodentia, Mammalia) from the Pliocene fauna of Osztramos 7. (N Hungary) by J. Hír HÍR, J. (1996): Cricetinus janossyi sp. n. (Rodentia, Mammalia) from the Pliocene fauna of Osztramos 7. (N Hungary).- Fragm. Min. et Pal., 18: 79-90. Abstract: The detailed metrical and morphological description of the new species is given with the systematic and stratigraphie relationships. INTRODUCTION The Osztramos Hill is situated near the northernmost point of Hungary in county Borsod-Abaúj-Zemplén between the villages Tornaszentandrás and Bódvarákó. The terra rossa, filling the fissures and the fossil caves of a big limestone quarry system, provided Plio-Pleistocene paleovertebrate faunas. The field activity for collecting the fossil materials took place during the 70's, under the guidance of Prof. Dénes JÁNOSSY. The locality no. 7 was regarded as a tectonic fissure by JÁNOSSY & KORDOS (1976). The aim of this paper is to give the accurate description of the "larger sized" hamster teeth. (The analysis of the "smaller sized" cricetids of Osztramos 7 is given in Hír 1994a). METHODS The description of the measuring practice is given in the earlier papers of the author in details (HÍR 1993a, 1993b, 1994a, 1994b) It is not reinterpreted, only demonstrated on Fig. 1. In the morphological examination the author followed the nomenclature of MEIN & FREUDENTHAL (1971a, b). SYSTEMATIC DESCRIPTION Order: Rodentia Bowdich, 1821 Family:Cricetidae Rochebrune, 1883 Subfamily: Cricetinae Murray, 1866 Genus: Cricetinus Zdansky, 1928
