“…Because of this change from vegetation to peat then coal, the assemblages of plants are often referred to as the coal forests. The fossil floras preserved in the coalfields of north‐western Europe have been intensively studied for over two centuries, making them among the best known Palaeozoic floras in the world (e.g., see Cleal, , , , ; Cleal, Opluštil, Thomas, & Tenchov, ; Cleal & Thomas, , ; Josten, ; Laveine, , for reviews). However, the plant biodiversity of some of the coalfields is less well known.…”

Plant fossils are recorded and described from Duckmantian clastic strata associated with coal seams in a small conserved area at Brymbo in the Wrexham (North Wales) coalfield. The exceptionally preserved flora consists of adpressions in mudstones, shales, and sandstones, more three‐dimensionally preserved plant remains in ironstone nodules, and three‐dimensionally preserved stems in their original positions of growth. The relationships of the plant fossils to the sediments are discussed and related to the varying conditions affecting the ecology of the area. Sometimes the influx of sediments was very rapid as can be seen by the numbers of erect and branching Calamites, arborescent lycophyte stems, and stigmarian bases preserved in sandstone in their original positions of growth.

West European regional chronostratigraphic stages and substages correlated with macrofloral biozones (Wagner 1984, Wagner & Álvarez-Vázquez 2010, Cleal 2018 are used throughout the paper instead the international chronostratigraphic stages defined dominantly on marine fauna in carbonate successions of east European Platform (Schneider et al 2020). The regional ("Heerlen") stages are well defined in the Czech part of the Intra-Sudetic Basin (Opluštil et al 2017) and radioisotopically cons trained (Opluštil et al 2016a).…”

Unpublished data resulting from extensive palynological investigation of coal and carbonaceous rocks from more than thirty boreholes, drilled in the Czech sector of the Intra-Sudetic Basin in the second half of the 20 th century, were taxonomically upgraded and analysed for stratigraphic and systematic evaluation. In total 78 genera and 322 miospore and pollen species have been recorded within a radioisotopically constrained ~21 Ma long interval from middle Bashkirian to early Asselian times, i.e. between 318 and 297 Ma. The miospore and pollen assemblages of coal seams are characteristic by the occurrence of stratigraphically important genera (e.g. Waltzispora, Radiizonates, Tripartites, Kosankeisporites, Gillespieisporites, Cadiospora, Angulisporites, Latensina, Lueckisporites, Spinosporites) and taxa recorded only within each member with the combination of quantitative data. Five new palynozones of the basin are recognised. All miospore and pollen taxa are divided into categories based on their plant affinity for the comparison of palynological and macrofloral records in terms of the diversity and vegetation patterns based on the combination of unpublished palynological and freshly published plant fossil records. • Key words: palynology, spores and pollen, Intra-Sudetic Basin, Pennsylvanian.Bek, J. & Opluštil, S. 2021.

The floristic relationship between the upland and lowland Carboniferous wetlands of Variscan Euramerica — Evidence from some medullosalean pteridosperm fronds

Alethopteris grandinii represents remains of fronds of a medullosalean pteridosperm (probably a small tree) that rapidly migrated across the lowland wetland habitats of Variscan Euramerica in middle Asturian (late Moscovian) times. This was probably caused by changing drainage patterns within the lowland coal swamps, in response to climate and landscape changes. However, these medullosaleans had first appeared rather earlier, in early Bolsovian (early Moscovian) times, in upland wetland habitats. These upland habitats may have pre-adapted these plants to the changed condition in the lowland coal swamps.
