Abstract

A conglomeratic sandstone, the lowest bed of the Taquaral Member, the basal unit of the Permian Irati Formation (Passa Dois Group), in the Municipality of Rio Claro, east-central State of São Paulo, Brazil, contains several species of vertebrate fossils. Chondrichthyes of different orders are represented by teeth and spines, but the most abundant fossils belong to the Osteichthyes as represented by paleoniscoid scales, teeth and bone fragments. The Actinopterygii are the commonest fish remains in this unit.
