Agua Formosa Creek road cut, 2m up (Cretaceous to of Brazil)

Also known as Mariliasuchus amarali referred material

Where: São Paulo, Brazil (22.3° S, 49.9° W: paleocoordinates 26.5° S, 33.1° W)

• coordinate stated in text

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

• 2 m up in the road section

•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).

• bed-level stratigraphic resolution

Environment/lithology: eolian; massive, fine-grained sandstone

• Sand sheet with reworked deposit of shallow ponds; Peripheral desert with sporadic (seasonal?) rainfall and restricted flooding in ephemeral ponds
• Massive fine grained sandsheet with brown shale intraclasts

Size class: macrofossils
