I „ni NE Fig. 2 Geological section of the trench P-ll/a, Vászoly The sequence in the upper part of the section is somewhat controversial, since Bed 16/A is represented by isolated blocks, mostly floating in the highest soft tuffaceous layer. However, its underlying position just below the Bed 16 seems to be evident. DISTRIBUTION OF THE FAUNA In the Vászoly section 18 beds were collected and studied thoroughly, of which 7 did not yield any identifiable fossils, but the others proved to be richly fossiliferous. Ammonites are usually preserved as internal moulds, while the brachiopods often bear shell remnants. The total number of specimens (including even the indeterminable fragments) is 1726, consisting mainly of ammonoids (821 specimens) and brachiopods (516 specimens). The bulk of the bivalves is originated from a thin Daonella shell-bed. The distribution of the major megafaunal groups is shown in Fig. 3. 50 taxa were separated, 35 of them were identified at species level. Nautiloids are represented by 1, ammonoids by 22 and brachiopods by 12 species. The vertical distribution of species and specimen number data is given in Table 1.
