Woodring Loc. 173 - eastern area [upper Gatun Fm] (Miocene of Panama)

Where: Panama (9.3° N, 79.9° W: paleocoordinates 9.1° N, 78.5° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• Upper part of the Gatun Formation. The Gatun Formation is sibdivided into three faunal zones (proposed by Thomson and Keen, 1946): lower, middle, and upper. 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 Sr dating for nearby sections indicates an age of approximately 9.5 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, fine-grained, silty sandstone

• No specific environmental data presented.
• LITHOLOGY: Siliciclastic. LITHIFICATION: Poorly-lithified, on the basis of figured specimens and outcrop observations.

Size class: macrofossils

Preservation: original aragonite

Reposited in the USNM

Collection methods: surface (in situ),

• COLLECTOR: Not stated in text. REPOSITORY: USNM.
