Pteridófilas pecopteróides da formação Rio do Rasto no estado do Paraná e da formação estrada nova no estado de São Paulo (Bacia do Paraná, permiano superior)

Abstract

This paper deals with Pteridophylla and Filicophyta from 23 outcrops of the Rio do Rasto Formation in Paraná State and 2 outcrops of the Estrada Nova Formation in São Paulo State (Passa Dois Group, Paraná Basin, Upper Permian). Equivalent fossils have been described previously from only 3 localities of these same stratigraphic units. The fossils occur as impressions of fragmented fronds and pinnae in red, gray and yellowish mudstones, siltstones and fine sandstones. All the better preserve d pecopterids correspond to new species: Pecopteris taguaiensis, P. dolianitii, P. esperancensis, P. bracatingaensis and P. cadeadensis. Other described specimens are considered as Pecopteris sp.1, P. sp.2, P. sp.3, ?Dizeugotheca bortoluzzii Cazzulo-Klepzig and? Dizeugotheca sp
