“…The miospore genera employed in the present study are organized in Table 1 approximately according to the suprageneric classification of Dettmann (1963) as modified by Neves & Owens (1966) and Smith & Butterworth (1967) but his terms are omitted to save space. The botanical affinities of the encountered taxa, to reconstruct the paleovegetation, are mentioned based on the available data obtained from Ravn (1986), Balme (1995), Azcuy et al (2002), Lindström (2003), Traverse (2007), Boardman et al (2012), Waksmundzka (2014), Di Pasquo & Iannuzzi (2015) and Mahesh et al (2016).…”

F OR THE FIRST time, a palynological assemblage was recovered from the Safi Formation in the west Beni Suef Basin of the Western Desert in Egypt. A total of 65 miospore taxa were recognized; they included 31 species of pteridophyte spores (related to 20 genera) and 34 species of gymnosperm pollen (related to 14 genera). The dominance of monosaccate pollen confirms an age not older than Westphalian (Late Carboniferous) as documented in various Gondwanan basins. Besides the restricted presence and limited counts of typical guide taeniate bisaccate and non-taeniate bisaccate pollen in the present assemblage constrain and limit the age to the Asselian (Early Permian) and not younger. The paleovegetation of the studied palynoassemblage is reconstructed based on the paleobotanical affinities of the identified miospores, which are generally consistent with other macrofloral fossil records obtained from Egyptian outcrops during the Late Carboniferous and Early Permian. The paleoecological significance of the reconstructed paleovegetation enabled the recognition of two paleofloral communities: A lowland paleoflora represented by a cold climate wetland fern community associated with Lycopsida and Sphenopsida and an upland paleoflora dominated by a primitive group of gymnospermic plants with a unique moistureindependent reproduction strategy developed under the influence of a glacial climate. The high representation of the bilaterally or radially symmetrical monosaccate pollen genera, which are typical Late Paleozoic Gondwanan gymnospermic vegetation, in the present material supports the hypothesis that Egypt's Western Desert was part of the Gondwanan floral province during the Late Carboniferous/Early Permian.

“…Botrychiopsis plantiana is documented from lower Permian strata on the eastern margin of the Paganzo Basin (e.g., Cúneo, 1986;Archangelsky et al, 1996) and in the Paraná Basin associated with the Gangamopteris Flora (Boardman et al, 2012). Botrychiopsis valida, the youngest species of western Gondwana, was originally described from Permian strata of India (Feistmantel, 1876(Feistmantel, , 1879 and Brazil (Jasper et al, 2003a;Guerra-Sommer et al, 2008), where it occurs together with Botrychiopsis plantiana (Boardman et al, 2012). As noted above, the Brazilian records of B. valida need to be confirmed with a revision of the Indian specimens.…”

Botrychiopsis is an important biostratigraphic index taxon for Carboniferousearly Permian plant fossil successions of Gondwana. Its species have wide geographic distributions, restricted chronostratigraphic ranges, and are associated with diverse groups of plants associations. They have been described from sedimentary sequences of Australia, India, South Africa, Brazil, and Argentina. A whole-frond reconstruction of Botrychiopsis plantiana is presented based on a study of very well preserved specimens from the Gangamopteris Flora (Ghzelian-Asselian) of the Bajo de Véliz Formation (Paganzo Basin, Argentina). The material consists of impressions of complete fronds and basal fragments, which are rarely represented in the Gondwanan upper Paleozoic fossil record.

“…This outcrop was divided into two distinct sedimentary units (Piccoli et al, 1991;Jasper et al, 2006) with two phytofossiliferous levels. The lower level of fossil plants from a dark gray massive mudstones that underlie a succession of thin coal seams, according to Piccoli et al (1991) and Guerra-Sommer et al (1995), Boardman and Iannuzzi (2010) and Boardman et al (2012), is predominantly composed of articulated stems (Paracalamites sp.) and Phyllothecalike leaf branches.…”

“…The upper level of phytofossils contain abundant stumps and stems of arborescent lycophytes in situ (Brasilodendron pedroanum), remains of pteridophylla fronds (Botrychiopsis valida, B. plantiana and Rhodeopteridium sp. ), fertile and sterile leafy shoots of conifers (Coricladus quiteriensis), rare leafy branches of lycopodiales (Lycopodites riograndensis), (Jasper et al, 2005;Jasper et al, 2006;Boardman et al, 2006;Guerra-Sommer et al, 2008;Tybusch and Iannuzzi, 2008;Iannuzzi and Boardman, 2008;Iannuzzi, 2010;Boardman et al, 2012). Iannuzzi (2010) placed the Quitéria floras in a stratigraphical interval at the transition from the Paraguaçu to Siderópolis members of the State of Santa Catarina, assigning an approximate age of 288-285 Ma (Artinskian, according Cohn et al, 2013, updated).…”

Apresenta-se aqui uma síntese da composição da paleoflora preservada em siltitos argilosos do Membro Siderópolis, Formação Rio Bonito tendo como objetivo estabelecer comparações fitoestratigráficas com outras paleofloras neopensilvanianas e cisuralianas da Bacia do Paraná. A Formação Rio Bonito, a mais importante das unidades litoestratigráficas portadoras de carvão da Bacia do Paraná, pertence à supersequência Gondwana I (Pensilvaniano-Eotriássico). A paleoflora Siderópolis ocorre nas camadas de carvão mais superiores da Formação Rio Bonito na região carvoeira de Santa Catarina, em quatro áreas distintas do Estado de Santa Catarina: Lauro Muller, Criciúma, São Marcos e Treviso. Na paleoflora, as folhas de glossopterídeas predominam com um evidente domínio do gênero Glossopteris sobre Gangamopteris, seguido por folhas cordaitaleanas (Noeggerathiopsis) e sementes (Cordaicarpus, Samaropsis, Cornucarpus). Frondes estéreis são comuns havendo poucas férteis (Sphenopteris, Pecopteris, Ponsotheca, Notoangaridium). Estruturas reprodutivas pteridospérmicas (Arberia, Arberiopsis, Ottokaria) e ramos de coníferas (Brasilocladus, Buriadia) são raros. Em relação a outras paleofloras da bacia, a de Siderópolis distingue-se por apresentar diversidade mais alta e muitos táxons exclusivos mostrando apenas umas poucas semelhanças com algumas paleofloras registradas no Rio Grande do Sul, ocorrendo em afloramentos do Rio Bonito tais como Morro do Papaléo (porção superior) e Quitéria. Essas diferenças podem refletir uma posição estratigráfica superior, mas pode também indicar diferenças em condições de sedimentação e / ou paleoecológicas.
