Where: São Paulo, Brazil (21.9° S, 51.4° W: paleocoordinates 26.0° S, 34.5° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Presidente Prudente Formation (Bauru Group), Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)
• Note that some authors (e.g. Piacentini Pinheiro et al. 2018) have regarded this unit as the Presidente Prudente Formation, but others refer it to the Adamantina Formation.
•
•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).
