Megaspores from coals of the Triunfo Member, Rio Bonito Formation (Lower Permian), northeastern Paraná State, Brazil
This paper presents the results of a detailed study of megaspores occurring in coal seams of the Triunfo Member, Rio Bonito Formation at Figueira, Paraná State, Brazil. This coal-bearing sequence accumulated in a marine delta system during the Early Permian. Four species are described and illustrate...

description | This paper presents the results of a detailed study of megaspores occurring in coal seams of the Triunfo Member, Rio Bonito Formation at Figueira, Paraná State, Brazil. This coal-bearing sequence accumulated in a marine delta system during the Early Permian. Four species are described and illustrated: Lagenoisporites triunfensis, L. scutiformis, Sublagenicula cf. brasiliensis, and Setosisporites cf. furcatus. Of these, the two species of Lagenoisporites are predominant. Relationships to other megaspore species are discussed; and the temporal and spatial distributions of the four species in the Paraná Basin are documented.<br>No presente trabalho são apresentados os resultados obtidos a partir do estudo sistemático detalhado dos megásporos provenientes das camadas de carvão do Membro Triunfo, Formação Rio Bonito, Estado do Paraná, Brasil. A seqüência portadora de carvão, foi o resultado do acúmulo de matéria orgânica num de sistema deltaico marinho durante o Eopermiano. Quatro espécies são aqui descritas e ilustradas: Lagenoisporites triunfensis, L. scutiformis, Sublagenicula cf. brasiliensis, e Setosisporites cf. furcatus. Destas, as duas espécies de Lagenoisporites são dominantes. São igualmente discutidas as relações existentes com outras espécies de megásporos, assim como documentada a distribuição temporal e espacial das quatro espécies na Bacia do Paraná. |
