Abstract

Baurusuchidae is one of the most diverse notosuchian groups, represented by ten formally described species from the Upper Cretaceous deposits of the Bauru and Neuquen basins, respectively in Brazil and Argentina. Among these, recent phylogenetic analyses placed Wargosuchus australis, Campinasuchus dinizi, and Pissarrachampsa sera within Pissarrachampsinae, whereas Baurusuchinae is composed by Aphaurosuchus escharafacies, Aplestosuchus sordidus, Baurusuchus albertoi, Baurusuchus pachecoi, Baurusuchus salgadoensis, and Stratiotosuchus maxhechti. All baurusuchines, except for Baurusuchus pachecoi and Stratiotosuchus maxhechti, were collected from the same locality of the Adamantina/Vale do Rio do Peixe Formation, i.e., Fazenda Buriti, near General Salgado, Sao Paulo. Recent works suggested that pissarrachampsines of that stratigraphic unit come only from outcrops in Minas Gerais, with a possibly older age equivalent to those of the Neuquen Basin members of the group. Here, we present a new Pissarrachampsinae specimen from Fazenda Sao Jose, a site near Fazenda Buriti, which challenges the proposed chronostratigraphic separation between the Sao Paulo and Minas Gerais baurusuchids, suggesting that both groups lived at about the same time.
