Abstract During the Palaeozoic Era, plants conquered land and covered greater areas from coastal lowlands to highlands. Palaeobotanical data based on macroremains Polish strata complete enrich picture of these processes. Knowledge about macrofloras developed significantly in last hundred years but is very unevenly distributed among successive geological periods. Ordovician Silurian macrofossils...
FALCON-LANG, H.J., BENTON, M.J., BRADDY, S.J. and DAVIES, S.J. 2006. The Pennsylvanian tropical biome reconstructed from the Joggins Formation of Nova Scotia, Canada. Journal of the Geological Society, London, 163, 561–576. FALCON-LANG, H.J. and BASHFORTH, A.R. 2005. Morphology, anatomy, and upland ecology of large cordaitalean trees from the Middle Pennsylvanian of Newfoundland. Review of Pala...
Characterisations of ‘‘hunter-gatherers’’ in Australia and ‘‘horticulturalists’’, or ‘‘agriculturalists’’, in New Guinea are familiar, and yet problematic. These terms are inadequate to convey the richness and diversity of subsistence practices across both regions, either for the recent pasts of ethnography and history, or for the distant pasts of archaeology (Harlan 1995); but they continue to...
Abstract Colluvial sediments originating from soil erosion on slopes have proven to constitute significant evidence for tracing past human impact mountain landscapes. In the Central European Erzgebirge (Ore) Mountains, colluvial are associated with specific landforms (footslopes, slope flattenings, dells) and cover a share of 11% (11,905 ha) regional landscape. Thirteen pedosedimentary sections...
Early–Middle Pennsylvanian (late Carboniferous) age coalbearing strata in Europe can be found in two general depositional settings (OPLUŠTIL & CLEAL, 2007; CLEAL et al., 2010, 2011). The most extensive deposits were formed in paralic settings, most notably on the Variscan Foreland and associated basins between the British Isles and northern Turkey, in the Donets Basin of eastern Europe, and the...
Fragmentary, indifferently preserved, and of low diversity plant remains occur in basal part of the Khoshyeilagh Formation, northern Shahrud, eastern Alborz Ranges. The oldest hitherto reported from Iran, the remains are essentially assignable to lycophytes and psilophytes. Additionally, spores retrieved from the Khoshyeilagh Formation with reference to available data on spore-plant relation-sh...
