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). |
Lithology and environment
Primary lithology: | sandstone |
Includes fossils? | Y |
Lithology description: The Adamantina Formation comprises massive to stratified sandstones and mudstones a lower, 2.5 m thick package of fine-grained massive to slightly stratified sandstone with calcite cement, including calcite nodules, coprolites, and the C. stenognathus holotype, which probably represents exposed sand bars in a fluvial braided system | |
Environment: | fluvial indet. |
Geology comments: Deposits of the Adamantina Formation are presently related to an alluvial system comprising lacustrine deltas and fluvial braided and meandering deposits, probably related with cycles of flooding events in the General Salgado area |
