The Westphalian macrofloral record from the cratonic central Pennines Basin, UK

Re-assessment of lithostratigraphy, biostratigraphy, and volcanic activity of the Late Paleozoic Intra-Sudetic, Krkonoše-Piedmont and Mnichovo Hradiště basins (Czech Republic) based on new U-Pb CA-ID-TIMS ages

“…The radioisotopic age of the 3 rd Strážkovice coal tonstein is thus in agreement with late Duckmantian macroflora of the Prkenný Důl-Žďárky Member (Šimůnek in Pešek et al 2001). Based on macrofloral criteria, however, the Duckmantian/Bolsovian boundary is virtually unrecognisable (Wagner 1984;Cleal 2005Cleal , 2007, which makes its identification in continental setting without marine bands impossible. Instead the base of the Paripteris linguaefolia Zone is often used to approximate the Duckmantian/Bolsovian boundary (Wagner 1984).…”

The Okmulgee, Oklahoma fossil flora, a Mazon Creek equivalent: Spatial conservatism in the composition of Middle Pennsylvanian wetland vegetation over 1100km

“…In contrast to many such floras described from Europe (e.g., Wagner, 1962Wagner, , 1971Thomas and Cleal, 2001;Cleal, 2004Cleal, , 2005Cleal, , 2007Cleal et al, 2004;Šimůnek, 2008;Libertín et al, 2009;Opluštil et al, 2009;Bashforth et al, 2010;Wagner and Álvarez-Vázquez, 2010), there are relatively few from the United States (Langford, 1958;Basson, 1968;Boneham, 1974;Gastaldo, 1977;Pheifer, 1979;Oleksyshyn, 1982;Wittry, 2006). The current study thus is a baseline that helps establish the composition and structure of coastal wetlands prior to the major changes in vegetation that took place at the Middle-Late Pennsylvanian boundary.…”

T0 peat-forming plant assemblage preserved in growth position by volcanic ash-fall: A case study from the Middle Pennsylvanian of the Czech Republic

“…Sphenopsids are represented by 5 species whereas cordaitaleans only by 1 species. Estimation of biological (whole plant) species is based on the fossil taxa representing organs that best characterise the diversity of particular plant groups (Cleal 2005). Lepidodendrid lycopsids are best identified by leafy shoots and/or bark compressions and are represented by Lepidodendron simile sensu Němejc (1947) lycopodioides Sternberg (1821) and Sigillaria sp.…”
