Fazenda Três Antas (lowermost level) (Cretaceous to of Brazil)

Also known as Três Antas Farm; FTA

Where: Minas Gerais, Brazil (19.5° S, 50.1° W: paleocoordinates 23.7° S, 33.0° 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).

•Lowermost level exposed at the FTA site, about four meters below the lowermost level bearing Campinasuchus dinizi and lepisosteiform remains

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; lithified, sandy sandstone

• Distal alluvial fans and alluvial plains subjected to sudden floods in a dry and hot climate
• Fine to coarse grained sandstones with calcrete surfaces, along with distinct levels of conglomeratic sandstones with alkali pebbles and sandstone intraclasts. The entire sequence shows convolute, fluidization and dish structures.

Size class: macrofossils
