Baurusuchidae is one of the most diverse notosuchian groups, represented by ten formally described species from the Upper Cretaceous deposits of the Bauru and Neuquén 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, São 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 Neuquén Basin members of the group. Here, we present a new Pissarrachampsinae specimen from Fazenda São José, a site near Fazenda Buriti, which challenges the proposed chronostratigraphic separation between the São Paulo and Minas Gerais baurusuchids, suggesting that both groups lived at about the same time.

Baurusuchidae 是最多样化的 notosuchian 群体之一，由来自分别位于巴西和阿根廷的 Bauru 和 Neuquén 盆地的上白垩统矿床的 10 种正式描述的物种代表。在这些之中，最近的系统发育分析置于座狼鳄属芦苇，Campinasuchus dinizi和Pissarrachampsa血清内Pissarrachampsinae，而Baurusuchinae由组成Aphaurosuchus escharafacies，Aplestosuchus sordidus，波罗鳄属albertoi，波罗鳄属pachecoi，波罗鳄属salgadoensis，和Stratiotosuchus maxhechti。除Baurusuchus pachecoi之外的所有baurusuchines和Stratiotosuchus maxhechti，采集自 Adamantina/Vale do Rio do Peixe 组的同一地点，即 Fazenda Buriti，靠近圣保罗的 Salgado 将军。最近的工作表明，该地层单元的 pissarrachampsine 仅来自米纳斯吉拉斯州的露头，其年龄可能与该组内乌肯盆地成员的年龄相当。在这里，我们展示了一个来自 Fazenda São José 的新 Pissarrachampsinae 标本，该地点位于 Fazenda Buriti 附近，它挑战了圣保罗和米纳斯吉拉斯州 baurusuchids 之间拟议的年代地层分离，表明这两个群体生活在大约同一时间。
