Sítio Myzobuchi, Álvares Machado (mudstone) (Cretaceous to of Brazil)

Also known as Santo Anastácio

Where: São Paulo, Brazil (21.9° S, 51.4° W: paleocoordinates 26.0° S, 34.5° 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).

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; mudstone and sandstone

• "a mudstone layer, truncated by a cross laminated sandstone, overlain by a congloimerate"

Size class: macrofossils

Collected in 1983

Collection methods: quarrying, surface (in situ), mechanical,
