Fazenda Furnas (Jales) (Cretaceous to of Brazil)

Also known as Furnas Farm

Where: São Paulo, Brazil (20.3° S, 50.5° W: paleocoordinates 24.5° S, 33.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Adamantina Formation (Bauru Group), Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)

• 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).

• formation-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; red sandstone

• "fluvial-lacustrine origin, deposited during times of warm and humid climates"
• "reddish muddy sandstones and subordinate conglomerates with mud intercalations" (Batezelli, 2015)

Size classes: macrofossils, mesofossils
