Dulai, A.: Middle Miocene (Badenian) lunulitiform Bryozoa from Szob (Börzsöny Mts., Hungary)

Cupularia Haidingeri, Szob (MANZONI 1877); Cupularia cfr. haidingeri, Rákospalota (FRANZENAU 1910); Lunulites sp., Nógrádszakái (BOGSCH 1936); Lunulites sp., Balassagyarmat (NOSZKY 1940); Cupularia (Lunulites) haidingeri, Acsa, Fót, Püspökhatvan (NOSZKY 1940); Lunulites sp., Rétság (BÁLDI et al. 1964); Lunulites sp., Fót, Csornád (HÁMOR 1985). These data indicate that lunulitiform Bryozoa are fairly common in the northern part of the Pannonian Basin. In the future the examination of the whole Pannonian Basin would be very instructive and interesting. Lunulitiform Bryozoa are more common in the Pannonian Basin than it was reflected in literature. A more detailed examination of this group is desirable in the area of the Pannonian Basin. Very useful data were given of the pal

eoenvironmental characteristics of Szob on the basis of the ecological features of lunulitiform Bryozoa before the examination of molluscs. Lunulitiform Bryozoa refer to soft sandy bottom below the wave base in normal or slightly reduced salty water in the tropical or subtropical climate.

The SEM photos were taken in the SEM Laboratory of the Hungarian Geological Survey by Mrs. TAKÁCS and Mrs. PELLÉRDY. Table 1.
