Atalaia (Miocene to of Brazil)

Also known as Salinopolis; Salinópolis

Where: Para, Brazil (0.6° S, 47.3° W: paleocoordinates 0.5° S, 44.5° W)

• coordinate stated in text

When: Pirabas Formation, Langhian to Langhian (16.0 - 11.6 Ma)

• Aguilera et al. (2020) considered the exposed fossiliferous levels of the Atalaia beach as late Langhian to Serravallian (14.2–12.7 Ma).

• formation-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithology not reported

• This sedimentary unit was deposited during the early to middle Miocene in coastal marine environments with a tidal regime, marginal lagoons with mangrove forests, and tropical storms, before the origin of the Amazon delta (Aguilera et al. 2020).

Size class: macrofossils
