seamounts were usually below the sublittoral zone (there are no calcareous algae in the material). The relatively high amount of Cardobairdia (12 %) indicates also a rather deep site of accumulation of sediments. Comparing the Carixian and Domerian fauna the decrease of the ornate Bairdids is visible (from 35 to 22 %) possibly caused by the further subsidence of the seamounts (Figs. 6-7). Fig. 6. Distribution of ostracods in the investigated Carixian samples. Legend: see in Fig. 5 Fig. 7. Distribution of ostracods in the investigated Domerian samples. Legend: see in Fig. 5 The Healdidae, which is one of the dominant groups of epicontinental fauna, are subordinate both in Carixian and Domerian samples. The most frequent genus is Bairdia (28-56 %).
