Abstract

The sandy facies at the base of the Taquaral Member, Irati Formation (earlyPermian, Artinskian), is noteworthy for its abundance of chondrichthyan fossils. However, to date just one species of Xenacanthiformes, Xenacanthus albuquerquei, has been published. Small teeth in this facies in an outcrop on the Santa Maria Homestead, Rio Claro Municipality, State of São Paulo, Brazil, are here assigned to two taxa, one to Xenacanthus sp. and the other as an indeterminate Xenacanthidae.
