Contribuição à estratigrafia da série Passa Dois no Estado do Paraná

Abstract: O trabalho versa o assunto da estratigrafia da série Passa Dois no Estado do Paraná, Sul do Brasil. Baseando-se nas próprias observações de campo e no exame da bibliográfia dedicada ao mesmo assunto, o autor analisa a estratigráfia dessa série geológica sob o ponto de vista [aciológico. Resume as pesquisas prévias, discute a posição da série Passa D ois, a sua espessura, tectônica, litologia, conteúdo paleontológico, idade, correlação, etc. N a parte dedicada ã paleontologia descritiva, apresenta uma revisão d… Show more

“…As we showed here, the original specimens of Petri & Fúlfaro (1966) are nicely preserved indeed, providing various key morphological features that are important in establishing its family affinities. Perhaps influenced by Mendes' studies of the Permian bivalves of the Paraná Basin (see Mendes, 1944Mendes, , 1952Mendes, , 1954, Petri & Fúlfaro (1966) left the question of family affinities of the genus Guiratingia open. It should be noted here that prior to the monographic study of Runnegar & Newell (1971), there was a generalized acceptance among Brazilian paleontologists that the bivalves of the middle and upper portions of the Permian succession of the Paraná Basin (LTPS-6 and 7, = Serra Alta, Teresina/Corumbataí and Rio do Rasto formations) were not similar to forms known outside the basin.…”

“…These deposits were predominantly generated under dysoxic to anoxic conditions (mainly below storm wave base) and are typically represented by massive to laminated mudstones (Schneider et al 1974;Ara ujo et al 2001;Meglhioratti 2006;Holz et al 2010). Except for a few occurrences of bivalves (Mendes 1949(Mendes , 1952(Mendes , 1954 molluscan fauna (Mendes 1952;Runnegar & Newell 1971;. This is claimed to be the oldest known example of a long-lived, molluscan fauna (Wesselingh 2007) that evolved within a large interior sea (>1,600,000 km 2 , Holz et al 2010) with restricted connections to the Panthalassa Ocean.…”
