Also known as Baurusuchus type; Riolandia, Paulo de Faria

Where: São Paulo, Brazil (20.3° S, 49.3° W: paleocoordinates 24.6° S, 32.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Adamantina Formation (Bauru Group), Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)

• Whereas a Turonian–Santonian age for the Adamantina Formation, based on ostracods and charophytes, has been proposed (Dias-Brito et al. 2001), other authors have argued for a Campanian–Maastrichtian age, based on vertebrate fossils and an alternative interpretation of the ostracod fauna (e.g. Gobbo-Rodrigues et al. 1999; Fernandes and Coimbra 2000). Most recently, stratigraphic work on the Bauru Basin has argued for a late Campanian–early Maastrichtian age for this stratigraphic unit (Batezelli 2017).
