Where: Costa Rica (8.0° N, 82.9° W: paleocoordinates 7.9° N, 82.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Charco Azul Formation, Pliocene (5.3 - 2.6 Ma)

• LITHOSTRATIGRAPHY: From Charco Azul Formation (Olsson 1942), which unconformably underlies the Armurelles Fm (Pleistocene).

• ENVIRONMENT: Deposited in deeper waters, probably between 100 and 400 fathoms.
• SPECIFIC LITHOLOGY: Soft tuffaceous shale. LITHIFICATION: Unlithified, base on figured specimens and lithologic description.

Size class: macrofossils
