Subdivision of the Lochkovian Stage based on conodont faunas from the stratotype area (Prague Synform, Czech Republic)

摘要: Relatively rich conodont faunas from sections in the Prague Synform (Barrandian area, Czech Republic) include a number of indexes and other important guide conodonts that can be correlated with regions, especially Nevada Spanish Central Pyrenees. The collation detailed correlation data Lochkovian two parallel Požary quarries, together biostratigraphic control additional several (incomplete) changing facies development, is basis for new regional biozonal scale Synform. subdivision follows, modification, global threefold Lochkovian. Data enable further lower, middle upper into small-scale units. distribution shows large proportional discrepancy between late elsewhere; record latest which appears to rather restricted requires discussion.
