Stratigraphy
Geological group:Bauru Formation:Adamantina
Stratigraphic resolution:bed
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).

Includes fossils?Y
Lithology description: "The outcrop exposes conglomeratic, medium and fine sandstones, with up to 1 cm quartz pebbles of yellowish to reddish color, though they are whitish at the base. Sandstones and shale clasts may also occur. Trough cross-beddings are observed in the conglomeratic sandstones with plane-parallel laminations, and small tabular cross-beds are observed in the fine ones."
Environment:terrestrial indet.
