Remarks on the palaeoenvironment One can separate the layers of the locality into two groups. The upper layers (1—2 and 3) were deposited in the Early Weichselian while the age of the lower layers (4, 5 and 6) is very probably Late Eemian. The remains of the layers show a bit mixed faunal composition. This is the result of two different phenomena. The stratification of the layers suggest that we have to reckon with some mixing of the deposits (GASP

ARIK 1993). The other reason is the mosaic palaeoenvironment. We have both floral and faunal evidences that the Carpathian Basin had rather mixed and diverse environments and vegetation during the whole Quaternary.
