“…High diversity is supported not only by the wide distribution of the plants but also by the enormous range of variability in their growth habits ( fig. 10A, 10B), from scrambling forms (Rothwell and Warner 1984), to small trees (Cridland 1964), to large, woody trees of tall stature (Falcon-Lang and Scott 2000;Falcon-Lang andBashforth 2004, 2005;Š imů nek et al 2009;Césari and Hü nicken 2013). The broad range of habitats encompassed by species of this lineage also suggests and is consistent with high species diversity (Š imů nek 2000,2007,2008); cordaitaleans were found throughout the Pennsylvanian tropical realm and were important in Cathyasian eastern Pangean floras during the Permian (Hilton et al 2009).…”

“…10D), perhaps during a change to greater rainfall seasonality at all phases of glacialinterglacial cycles (Cecil 1990;Bashforth et al 2014), and became an increasingly important element of these kinds of assemblages (Galtier et al 1992;Rothwell et al 1997;Hernandez-Castillo et al 2001b;Blake et al 2002;Falcon-Lang et al 2009;Plotnick et al 2009). Plants of both lineages are coniferophytes and had strongly xeromorphic morphological features (Clement-Westerhof 1988;Rothwell et al 1997;Š imů nek 2000Š imů nek et al 2009). They are accompanied in the better-preserved assemblages by various elements not typically found in wetland floras.…”

“…The seasonally dry plants then invaded basins, cratonic or intermontane, during times of climate change in those basinal locations (Elias in Moore et al 1936;Arnold 1941;DiMichele and Aronson 1992;Calder 1994;Gastaldo 1996;Blake et al 2002;Ziegler et al 2002;Š imů nek and Martínek 2009;Opluš-til et al 2013b;Tabor et al 2013b). This view differs from the strictly upland view in that it explicitly includes a climatic element in the equation and recognizes that the natural landscape is climatically complex, biome distributions being mainly reflective of climatic patterns, primarily the interaction of climate and rainfall (Kö ppen 1936;Walter 1985).…”

Premise of research. The Late Paleozoic Ice Age was the last extensive pre-Pleistocene ice age. It includes many climate changes of different intensities, permitting examination of many and varied biotic responses. The tropical Pennsylvanian Subperiod, usually visualized as one vast wetland coal forest, in fact also was dominated, periodically, by seasonally dry vegetation that, in turn, covered most of the central and western Pangean supercontinent. Equatorial wetland and dryland biomes oscillated during single glacial-interglacial cycles. This recognition changes understanding of the Coal Age tropics; examination of their spatiotemporal patterns indicates that these vegetation types responded differently to global environmental disturbances and long-term trends and points to potentially different underlying controls on evolutionary histories of their component lineages.Methodology. This study is based on the published literature and on examination of geological exposures and fossil floras, mainly from North America but also from other parts of the world.Pivotal results. Wetlands and seasonally dry habitats were equally part of the Coal Age Pangean tropics. They dominated these landscapes at different times, under different climatic regimes. Wetland vegetation was likely forced into refugia during seasonally dry (subhumid to semiarid) parts of glacial-interglacial cycles; it reemerged/reassembled during wet (humid to perhumid) periods. Seasonally dry vegetation resided permanently in areas of western and central Pangea and in microhabitats within the Central Pangean Mountains. Both floras had lower biodiversity than modern floras in similar habitats. The wetland flora species pool was more phylogenetically disparate than any modern vegetation. In contrast, seasonally dry floras were dominated by seed plants. These biomes responded differently to acute environmental changes and chronic long-term aridification.Conclusions. From ecological or evolutionary perspectives, the present-day world is but one possibility. Lower-diversity worlds such as the late Paleozoic, with a rich spectrum of environmental variations, offer insights into relationships between organisms and environments that expand understanding of these phenomena and enlarge our sense of what is possible or probable as we look to the future.

“…Some are characteristic of high substrate moisture, such as calamitaleans, tree ferns, and the pteridosperm Macroneuropteris scheuchzeri (Stull et al, 2012). Others are characteristically drawn from what are often inferred to be mesic but seasonally dry settings, such as the odontopterids and mixoneurids Ziegler et al, 2002;Šimůnek and Martínek, 2009), whereas others are considered to be indicators of more strongly seasonally dry settings, such as the conifers (DiMichele and Aronson, 1992;Šimůnek and Martínek, 2009;Opluštil et al, 2013). This kind of mixture is often attributed to vegetational zonation on a landscape, reflective of soil drainage (e.g., Dimitrova et al, 2011).…”

“…Unfortunately, as will be discussed below, the disposition of the field notebooks associated with these collections is not known, forcing us to rely on secondary sources to assess the stratigraphic interval covered by the collections. The fossil assemblages compare most closely with those described from the Pennsylvanian-Permian boundary elsewhere in Euramerica, including the Dunkard of the U.S. Appalachian Basin (Blake and Gillespie, 2011), Rotliegend of Germany (e.g., Potonié, 1893;Barthel, 1976Barthel, , 2009Kerp and Fichter, 1985;Barthel and Brauner, 2015), the Autunian of France (e.g., Zeiller, 1890Zeiller, , 1892Zeiller, , 1898Zeiller, , 1906Doubinger, 1956;Broutin, 1995, 2008;Steyer et al, 2000;Bercovici and Broutin, 2008), and other European strata that encompass the Pennsylvanian-Permian transition (e.g., Broutin, 1981;van Amerom et al, 1993;Wagner and Martínez García, 1982;Popa, 1999;Šimůnek and Martínek, 2009). …”

A new Late Pennsylvanian floral assemblage from the Douro Basin, Portugal

The Douro Basin (lower Gzhelian/lower Stephanian C, Upper Pennsylvanian; NW Portugal) is one of the richest continental sedimentary basins in fossil floras of late Carboniferous age in Portugal. Recent field work carried out in the Douro Basin allowed to report a new fossil site, of potential Lagerstätte quality, found in the Montes da Costa (Ermesinde) region. This new fossil locality preserves exceptional palaeontological, stratigraphic, lithological, and tectonic structural features of great scientific interest. An exceptional record of sudden catastrophic flooding events represents one of the most remarkable geological records documented in this new locality. In the palaeontological context, the plant assemblage described comprises a well‐preserved and very diversified macroflora of early Gzhelian age, consisting of several fossil taxa belonging mainly to genera and species of Pteridopsida, Pteridospermopsida, and Sphenopsida. Its fossil records are essentially parautochthonous deposits, but several Calamites trunks preserved in autochthonous position were documented. Within the studied plant assemblage, a new species of arborescent marattialean fern, Acitheca murphyi sp. nov., is described, and several new floral occurrences are first reported in the Portuguese Carboniferous. Here, we analyse the palaeoecological, palaeoenvironmental, and palaeoclimatic conditions of the new palaeobotanical data. Additionally, there was undertaken an extensive comparative study of Gzhelian (Stephanian C–early Autunian) age macrofloras from different localities of Europe and North America. Together with these results, a significant macrofloral biostratigraphic gap for the Kasimovian stage in the Appalachian region (West Virginia, USA) is demonstrated to be correlated to the Late Pennsylvanian of Portugal, and its palaeogeographic significance is assessed.
