Where: Para, Brazil (0.8° S, 47.1° W: paleocoordinates 0.8° S, 43.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Pirabas Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• Horizontal beds of limestone near sea level. Closely associated with faunas of the Gatun, Bowden, and the Gurabo and Cercado Fm, but containing Orthaulax, which is not recorded in beds younger than the Chipola Fm of Florida, older than the above units. It is also present in the Baitoa Fm of the Dominican Republic. Maury (1924) therefore considered the fauna to be of Early Miocene age. Also shows close affinities to the Aquitanian srafe of France. Maury correlates this unit to the Chipola Fm of Florida and the Aquitanian of France. This was the lowest unit yet identified in the Neogene of Brazil. Early Miocene in Vokes (1990), and is accordingly assigned to Early Miocene here.
