The first notosuchian crocodyliform from the Araçatuba Formation (Bauru Group, Paraná Basin), and diversification of sphagesaurians

The mesoeucrocodylian record from the Bauru Group (Paraná Basin, Brazil) comes three formations: Adamantina (Late Turonian–Early Maastrichtian), Presidente Prudente (Early Campanian–Early Maastrichtian) and Marília (Maastrichtian). These records are restricted to Early Coniacian–Early Maastrichtian. Here, we report a new crocodyliform Group, which was first of Araçatuba Formation, locality Coronel Goulart district, in Álvares Machado municipality. Coronelsuchus civali gen. nov. et sp. comprises two related specimens - FFP PG 13 14 recovered close each other on same muddy sandstone level. We perform phylogenetic analysis with 392 characters (five added) 88 taxa. Our analyses supported clades: Sphagesauria, Sphagesaurinae Caipirasuchinae. results suggest C. as basal Sphagesauria. Regarding Crocodyliform Assemblage Zones (CAZ), species is correlated CAZ 1, together small sphagesaurians, Caryonosuchus itasuchids. reveals an older appearing (pre-Turonian) diversification also expand stratigraphic range for Notosuchia Group.
