Abstract A synthesis of the upper Moscovian sedimentological and palaeontological record terrestrial habitats across Variscan foreland adjacent intramontane basins (an area which is referred to here as Euramerica) suggests a contraction progressive westward shift coal swamps. These changes can be correlated with pulses tectonic activity (tectonic phases) resulting from northwards migration Front. This caused disruption landscapes drainage patterns where swamps were growing, became less...
The Serpukhovian (Namurian A) stratigraphy of the Ostrava Formation, Upper Silesian Coal Basin, Czech Republic, consists coal-bearing paralic sediments underlain by marine deposits in a cyclothemic nature similar to those Pennsylvanian Euramerica. thickness formation exceeds 3000 m, which >170 coals are identified foreland basin setting. Fifty-five genetic cycles present study, using transgressional erosional surfaces as lower and upper boundaries. Terrestrial plant-macrofossil assemblages...
A Middle Pennsylvanian tuff bed (the Bělka bed) in the roof of Lower Radnice Coal bears T 0 peat-forming vegetation preserved growth position.This has been studied detail at 12 hectares large Ovčín coal deposit southern part Basin.Documentation fossil record six excavations and that previously collected former opencast mine allowed for a detailed reconstruction local lepidodendrid-cordaitalean forest structured into well-developed stories.It consists about 33 species, which colonized...
A three-dimensional reconstruction is provided of the composition, spatial distribution, and structure a single-aged, Middle Pennsylvanian (Moscovian) peat-forming forest high-ash, planar (rheotrophic) mire, buried in situ by volcanic ash preserved Lower Radnice Coal Basin (Czech Republic). The based on detailed taxonomic taphonomic analysis fossils ∼0.5-m-thick tuff bed at base Whetstone Horizon excavated over an area 93.5 m 2 . In all, 24 whole-plant taxa various growth forms were...
The remains of cordaitalean plants are an important element in Bolsovian plant fossil assemblages from the Radnice Basin (Czech Republic).The study historic collections and new excavations brings together data on Cordaites type species -Cordaites borassifolius.Cordaites borassifolius was probably quite a large tree monopodial or even sympodial stature.Its trunk diameter at minimum 0.5 m.Branches were between 1.1 m spaced less than 0.7 appart.The bases branches usually attained about 2/3 to...
Abstract The depositional environment, hydrology and vegetational history of the Lower Radnice Coal (Duckmantian) in Kladno coalfield was studied using sedimentary geology, coal petrology paleobotanical/palynological methods. peat accumulating wetland formed a fluvial paleovalley approximately 15 km long 2–5 wide, bordered by basement paleohighs landlocked interior central European Variscides. swamp evolved on top mud-dominated floodplain successions pedogenically modified to vertic gleyed...
The Douro Basin (lower Gzhelian/lower Stephanian C, Upper Pennsylvanian; NW Portugal) is one of the richest continental sedimentary basins in fossil floras late Carboniferous age Portugal. Recent field work carried out allowed to report a new site, potential Lagerstätte quality, found Montes da Costa (Ermesinde) region. This locality preserves exceptional palaeontological, stratigraphic, lithological, and tectonic structural features great scientific interest. An record sudden catastrophic...
The Carboniferous – early Permian plant genus Lesleya is a characteristic component of “dryland floras” that occupied wide range moisture-stressed, well-drained environments in tropical regions Euramerica. Fossil records are almost exclusively found basinal lowlands. For example, occurrences Early Pennsylvanian-age, seasonally dry, parautochthonous deposits lowlands North America (e.g., Illinois Basin, USA) indicate lived region low-altitude (lowland) paleoenvironments during dry climatic...
A significant vegetational change occurs in the Late Mississippian (Serpukhovian, Namurian A) across Enna Marine Zone (EMZ), Upper Silesian Basin, Czech Republic. All plant clades were impacted, including both spore-producing and seed-producing taxa; wetland taxa unaffected. Similar responses are not identified elsewhere although, basinwide, thick marine zones (e.g., Barbora Zone, BMZ) also developed at various times during Serpukhovian. Examination of sedimentological petrophysical...
Abstract: The cone genus Discinites is revised based on 31 specimens belonging to seven species collected from the Kladno-Rakovník, Radnice and Lísek continental basins of central western Bohemia, Czech Republic. stratigraphical distribution cones studied ranges Bolsovian Westphalian D. Emendations hlizae bohemicus are proposed. A new species, nemejcii, erected. Wherever possible descriptions in situ microspores megaspores included diagnoses. Isolated represent two ontogenetic stages....
