Stratigraphy
Geological group:Bauru Formation:Adamantina
Stratigraphic resolution:group of beds
Stratigraphy comments: 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).
