September 21, 2022
The Czech Geological Survey published the work Calcareous Nannofossils. Upper Cretaceous of the Bohemian Cretaceous Basin and the Outer Western Carpathians by Lilian Švábenická.
It gives a comprehensive overview of calcareous nannofossils and mutual biostratigraphic correlations for the Cenomanian–Coniacian epicontinental deposits of the Bohemian Cretaceous Basin and the Cenomanian–Maastrichtian mostly flysch strata of the Outer Western Carpathians in the territory of the Czech Republic. The attention is paid to nannofossil record in boundary intervals of the Upper Cretaceous stages including the Albian-Cenomanian and the Maastrichtian-Danian, to pulses in abundance of Braarudosphaera bigelowii as a reflection of coastal paleoenvironment, and to gradual penetration of high-latitude taxa into the NW part of Tethys during Campanian and Maastrichtian. A comparison with assemblages in the Gosau Group, Northern Calcareous Alps is also mentioned.
The book contains 14 figures of geological schemes with site locations and biostratighraphic correlations, 12 distribution tables and 15 plates of microphotographs of nannofossil taxa.
