Also known as USGS 6006

Where: Panama (9.3° N, 79.9° W: paleocoordinates 9.0° N, 78.5° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• Middle part of the Gatun Formation. The Gatun Formation is subdivided 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 Sr dating for nearby sections indicates an age of approximately 10.1 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

Environment/lithology: marine; unlithified, fine-grained, silty sandstone

Size class: macrofossils

Reposited in the USNM

Collection methods: surface (in situ),

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