First record of Siluriformes from the northernmost portion of the Bauru Group (Upper Cretaceous) in the Center-West region of Brazil

This work presents the first record of bony fish from the Maastrichtian of the Mar & iacute;lia Formation (Bauru Group) in Goi & aacute;s State, Brazil. A fragment of a pectoral spine, recovered by screen-washing, clearly represents an important catfish (Siluriformes) record from the Late Cretaceous of South America. The material possesses similarities with forms from the Campanian - early-Maastrichtian of the Adamantina Formation and the Maastrichtian of the Mar & iacute;lia (S & atilde;o Paulo State) and El Molino (Bolivia) formations. Inclusion of the new material from Goi & aacute;s in the dataset for the aforementioned areas within a paleoenvironmental setting provides evidence that Late Cretaceous catfish had a wider distribution than previously known.
