I have to mention here that

, according to the evidence of the recently cleened, very well preserved remains of Mimomys from Locality 3 of Osztramos (JÁN0SSY, 1970; skulls fossilized often together with the mandibles), the determination of some Oldest or Early Pleistocene voles as "Clethrionomys sp.", "Pliomys episcopa.lis" - "kretzoii" - "lenki" are not correct. All identifications are to be corrected on the basis of upper dentitions. One might say that all these form doubtless belong to Mimomys-group

, however, we probably have to divide this genus into subgenera (see fig. 2). But to return to our original sketch of the faunistic picture of the assemblage of locality 7, Osztramos: Baranomys lóczy

i, Germanomy

s (?= Stachomys), Cricetinu

s and Dryomimu

s are typical Upper Pliocene genera and there occur in the characteristic Uppermost Pliocene faunas as Csarnóta, Weze etc. The further species are stratigraphically more or less indifferent (or not surviving the Lowest Pleistocene), such as Talpa, Desman

a, Apodemus, Pliopetaurista

, Pliopete

s, Glis mino

r,

Grilurus pusillu

s, Cricetinu

s, Prospala

x, Hypolagu

s etc. Among large mammals seems to be significant a basal fragment of an antler of a deer,which looks like Cervodama pontic

a PLEROW et PIDOPLITCHKO and proves the stratigraphical position of this form. The special Eomyid, described from the considerably younger locality 3, Osztramos (Lower Pleistocene), Estramomys simplex JMOSSY, 1969 - perhaps a special local form of the Northern Carpathian Belt - is present also in locality 7 (stratigraphical sketch see tab. 1.). The most significant element of this fauna - from our point of view - is the heretofore known oldest Lemmu

s remain in Europe. This species indicates the perhaps first deterioration of the climate at the base of the Pleistocene of Europe . Although the northern character of the recent members of the genus Lemmu

s is not quite unambiguous, it seems to have been a northern and atlantic element in Europe during the Pleistocene . The lack of lemmings in the faunas of the Submediterranean Mountains Villány and the presence of Dolomy

s and Propliomy
