Bivak cave

The Bivak cave, already mentioned above in connection with its lower strata, is situated on the other (northwestern) side of the Pilis Hill. Two Gravettian implements of non-cave nature (Vertes, 1965, p. 195) have been found in its upper loessy layer. The rodent fauna is very similar in composition to that of rock shelter no. 1 of Pilisszanto [arctic lemming Dicrostonyx), snow vole, and the narrow-skulled vole Microtus nivalis and gregalis) (twice as many specimens as the former two)], but in the large-mammal fauna the cave bear (U. spelaeus) predominates. Thus, since the two localities are so close geographically, the differences that exist between the two faunas are due to stratigraphical rather than facies differences. The yellowish stratum of the Bivak cave must certainly be dated as older than Pilisszanto no. 1.
