  • Descrição: Dispersed miospore and pollen assemblages from the Krkonoše-Piedmont Basin were described from the Syřenov, Semily and Vrchlabí formations, i.e. Gzhelian to Asselian age. The assemblage consists of 73 genera with 218 species. General trend from stratigraphically older to younger strata is increasing number of monolete miospores and pollen. The most typical is abundance of Lycospora, Polymorphisporites, Cadiospora, Triquitrites and number of smallest laevigate spores of genera Laevigatosporites, Latosporites, Punctatosporites, Torispora, Thymospora and Speciososporites. The most typical pollen are Florinites, Wilsonites, Potonieisporites, Kosankeisporites, Candidispora, Guthoerlisporites, Vitattina and Nuskoisporites. The reconstruction of vegetation and palynological comparison with other Czech and European coalfields and basins have been made. •Development of coal-forming vegetation during late Paleozoic.•Floristic changes within coal seams based on dispersed spore record.•Spore ranges are plotted against radioisotopically calibrated lithostratigraphy.•201 miospore species have been identified within a 6.2 My long interval.
