The Brazilian eogondwanic floral succession

A stratigraphic chart of the Late Carboniferous/Permian succession of the eastern border of the Paraná Basin, Brazil, South America

“…The Late Carboniferous flora was previously denominated as Taphoflora A, by Rösler (1978), and later as PreGlossopteris Flora, by Iannuzzi and Souza (2005). This flora occurs as compressed-impressed plant remains in only few localities of São Paulo, having been recovered from the lowermost to the middle Itararé Group.…”

“…It corresponds to the ''Transitional" or Taphoflora ''A-B" of Rösler (1978). This flora also occurs in few localities but is widely spread through the eastern margin of the Basin, having been found in localities from the uppermost Itararé situated in São Paulo and Rio Grande do Sul.…”

“…In few localities of the Paraná Basin, there are occurrences of some typical elements (bivalves) related to Australian ''Eurydesma Fauna", recovered from the upper part of the Itararé Group (RochaCampos and Rösler, 1978). The ''Eurydesma Fauna" is considered throughout Gondwana deposits as earliest Permian, e.g., Asselian -Early Sakmarian interval (Iannuzzi and Souza, 2005;Iannuzzi, 2007).…”

The Botrychiopsis genus and its biostratigraphic implications in Southern Paraná Basin

“…On the informal phytostratigraphic zonation of the Late Paleozoic Paraná Basin, Rösler (1978) recorded the presence of Botrychiopsis plantiana in Taphoflora A, relating it to the early stages of deglaciation in the Paraná Basin (Sakmarian/ Artinskian). Andreis and Archangelsky (1996), in a review of the Neopaleozoic basins of South America, related the Taphoflora A to a probable Stephanian age, taking into account the lack of the Glossopteris genus.…”

“…Andreis and Archangelsky (1996), in a review of the Neopaleozoic basins of South America, related the Taphoflora A to a probable Stephanian age, taking into account the lack of the Glossopteris genus. According to Guerra-Sommer and Cazzulo-Klepzig (1981) the Itararé Group taphoflora in the Rio Grande do Sul State, including Botrychiopsis plantiana, can be related to the Cerquilho (Taphoflora A and B of Rösler 1978) and Argentinean Bajo de Veliz (Lubekense A) taphoflora.…”
