TU 961 - Cativa [lower Gatun Fm] (Miocene of Panama)

Where: Panama (9.4° N, 79.8° W: paleocoordinates 9.1° N, 78.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: lower Gatun Member (Gatun Formation), Tortonian (11.6 - 7.2 Ma)

• STRATIGRAPHIC RELATIONS: From the Gatun Fm, which regionally overlies the Caimito Fm or Mesozoic basement. AGE: Late Miocene, on the basis of microfossil biostratigraphy (see Collins and Coates, 1999), refined by enterer to Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 11.1 Ma (Hendy, unpublished data).. STRATIGRAPHIC POSITION: From unknown position within formation.

• bed-level stratigraphic resolution

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

• ENVIRONMENT: Shallow-marine, siliciclastic environment.

• SPECIFIC LITHOLOGY: Sandy mudstone. LITHIFICATION: Poorly-lithified, based on observations of material.

Size class: macrofossils

Preservation: original aragonite
