Armuelles Formation (unspecified localities) (Pleistocene of Panama)

Where: Panama (8.3° N, 82.9° W: paleocoordinates 8.2° N, 82.6° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Armuelles Formation (Charco Azul Group), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• LITHOSTRATIGRAPHY: From the Armuelles Formation. AGE: Pleistocene, according to Ingle (1985) on the basis of microfossils; direct date estimated based on other collections from the Armuelles Formation. STRATIGRAPHIC POSITION: From unknown position within section.

• formation-level stratigraphic resolution

Environment/lithology: coastal; unlithified, shelly/skeletal, sandy conglomerate

• ENVIRONMENT: Typical shallow water assemblage, very similar to that living in near-shore waters along the present coast of Panama.
• SPECIFIC LITHOLOGY: Beds are quite sandy and soft. LITHIFICATION: Unlithified, base on lithologic description.

Size class: macrofossils

Reposited in the PRI
