Palynological contribution to the study of the Itararé Subgroup at Serra dos Paes, south of the State of São Paulo

Abstract

Fifteen sporomorphs have been recorded from the upper portion of the Itararé Subgroup, Paraná Basin, at Serra dos Paes, south of São Paulo State, Btazil. This represents the first palynological record for the locality. The palynological assemblage is rich in taeniate bisaccate and poliplicat pollen grains such as Protohaploxypinus, Vittatina and Complexisporites, whereas spores and non-taeniate (mono and bisaccate) pollen grains are scarce. Two taxa are presented for the first time in the Brazilian Paraná Basin: Granulatisporites austroamericanus Archangelsky & Gamerro and Protohaploxypinus panaki Utting. According to the palynological data and to correlations with similar Gondwanic assemblages, the age of the assemblage is considered to be early Early Permian (Sakmarian).
