The studied sequence outcrops at Faxinai locality, Barão do Triunfo sheet, and belongs to the silty-sand facies of the Itararé Group. The facies represents a lacustrine environment with periodical fluctuations of the borders. The taphoflorula consists of the genera Rubidgea, Paracalamites, Cordaites, Buriadia, Glossopteris, Cordaicarpus and Samaropsis. The palynological assemblage is composed of Punctatisporites, Granulatisporites, Calamospora, Leiotriletes, Cristatisporites (Pteridophyta), Potoniesporites and Pilacopollenites (Gymnospermae), the Glossopteridophyta scarcely being represented. Micro and macroflórula relationships are recognized, allowing the definitian of a Sakmarian age for the associations.
