Annotation: 

Robust sets of mostly unevaluated and unpublished data and material on macroflora and palynomorphs will be re-examined to produce high-resolution biostratigraphic record of the Late Palaeozoic basins in the Bohemian Massif. This in the combination with high-precision radiometric data obtained from syndepositional tuff beds will serve to study floristic dynamics in a detail within an interval from the Serpukhovian to the Sakmarian (~43 My) as a response to the onset of the Late Palaeozoic Ice Age and related climatic oscillations operating on several scales including high-frequency Milankovitch cyclicity to general trend of increasing aridity and potentially also to tectonic processes. In combination with high-precision radiometric ages of volcanoclastics these data will serve for detailed correlations with paralic basins of Eastern Europe where high-resolution biostratigraphy and radiometric dating exist. Radiometric data further improve parallelization of regional and global chronostratigraphic charts and their calibration with radiometric ages.
