The Irati Formation, Permian (Cisuralian) of the Paraná Basin, stands out for important geological and paleontological characteristics. Two members are recognized, Taquaral and Assistência. Most of the Taquaral Member is composed of silty-clayey, gray sediments with plane-parallel laminations and at the base there are conglomeratic sandstones with large numbers of vertebrate fossils. The Cabeça River outcrop has the greatest thickness of the sandy facies, 43cm, the others are 9.5 and 15cm thick, but the lowest fossil density, 0,5fossil/cm². The present work discusses and characterizes the taphonomy and paleoictiofauna of this outcrop. Most fossils are teeth, scales and indeterminate bone parts of Actinopterygii (Palaeonisciformes) and indeterminate Xenacanthiformes teeth.

AbstractThe Permian (Cisuralian) Irati Formation, from the Brazilian southeastern Paraná Basin bears, at some levels, Chondrichthyes, besides other vertebrates. Outcrops of this unit are frequent at the state of São Paulo eastern belt. Two members of the Irati are recognized at this state, Assistência, the upper, and Taquaral. A sandy facies, mostly at the base of the Taquaral, is noteworthy by the richness of the Chondrichthyes, mainly Holocephali. The Petalodontiformes are the Chondrichthyes most abundant, so far referred to Itapyrodus punctatus. Recent studies of several specimens revealed that some morphotypes must belong to different species of the genus Itapyrodus. Others are akin to this genus, justifying a proposition of an endemic family Itapyrodidae. The presence of this endemic family is an argument, among others, for a proposed isolation of two Brazilan Basins northeast Parnaíba and southeast Paraná, during the time of deposition of the Irati, inasmuch as Itapyrodidae are present in both basins.
