Coordinates: 19.5° South, 49.2° West (view map)
Paleocoordinates:23.7° South, 32.1° West
Basis of coordinate:stated in text
Geographic resolution:small collection
Time
Period:Cretaceous Epoch:Late/Upper Cretaceous
Key time interval:Late/Upper Campanian - Early/Lower Maastrichtian
Age range of interval:83.60000 - 66.00000 m.y. ago
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).
