Foraminiferová společenstva z vrtu HV-5 Rybníček

Abstract

The HV-5 Rybníček borehole was drilled in south part of Rybníček village. Lower Badenian foraminiferal assemblages were studied. Their composition has two main characters: changes in plankton/benthos ratio and variation in diversified and impoverished assemblages. Euryoxybiont taxa are usually dominant, e.g. Bulimina div. sp., Bolivina div. sp., Praeglobobulimina div. sp., Uvigerina div. sp. and Stilostomella div. sp. It can refer to the seasonal changes of oxygen level at a sea bottom
