Woodring Loc. 176 - Margarita [Gatun Fm] (Miocene of Panama)

Also known as USGS 8358; WG176

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

• coordinate estimated from map

• outcrop-level geographic resolution

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

• LITHOSTRATIGRAPHY: From the upper 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 Sr dating for nearby sections indicates an age of approximately 9.5 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

Environment/lithology: marine; poorly lithified siltstone and poorly lithified, silty sandstone

• No specific environmental data presented.
• LITHOLOGY: Siltstone and silty sandstone.

Size class: macrofossils

Preservation: original aragonite

Collected by Olsson in 1918; reposited in the USNM

Collection methods: surface (float), surface (in situ),
