Where: Atlantico, Colombia (10.8° N, 75.0° W: paleocoordinates 10.1° N, 72.4° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Middle Miocene (16.0 - 11.6 Ma)

• Marl. Middle Miocene age based on correlation with other Caribbean fossil assemblages and by stratigraphic relations.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified, brown marl

• No paleonenvironmental data reported, though from apparently from shallow-water siliciclastic sediments.
