Abstract (in english)
   Working on biostratigraphy of the late Silurian and of the early Devonian by means of conodont successions from Bohemia and other regions, we realize that the relevant modern literature conveys several problematic opinions and practices of identification and zonation. Global applications of the zonal concepts concerning the so-called standard conodont zones eosteinhornensis, remscheidensis, detorta and woschmidti-hesperius are questioned. New correlations are based on conodont faunas from the Požáry section (the stratotype of the Přídolí Series, Barrandian) and the Elbersreuth Orthoceratid Limestone (Frankenwald); they enable links to Baltic conodont faunas. Based on our studies, we came to the following conclusions: The late Silurian development of spathognathodontan conodont taxa requires a more detailed taxonomic subdivision than has been practised hithertho. Biostratigraphical controls must not only rely on conodonts against other evidence.
