Dynamics of the Upper Ordovician climax-stage faunal assemblages before global crisis controlled by climatic changes: a record from the Králův Dvůr Formation of the Barrandian area

The Králův Dvůr Formation represents an important lithostratigraphic unit of the Ordovician in the Prague Basin (Barrandian area). Widely extended and important changes in sedimentary and fossil record took place during its sedimentation. Trends in biodiversity dynamics are particularly substantial for understanding all effects of the Late Ordovician global climatic changes. Such knowledge is of actualistic significance for models of modern climatic changes. In spite of worldwide interest in study of global changes in the Late Ordovician, not very intense attention has been paid to upper Katian in the Prague Basin. The proposed project is focused on filling of this information gap.
