Woodring Loc. 144 - Camp Cotton [middle Gatun Fm] (Miocene of Panama)

Also known as USGS 6029a; WG144

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

• coordinate estimated from map

• outcrop-level geographic resolution

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

• LITHOSTRATIGRAPHY: From middle 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 Sr dating for nearby sections indicates an age of approximately 10.4 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

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

• No specific environmental data presented.
• LITHOLOGY: Soft, silty fine-grained sandstone.

Size class: macrofossils

Preservation: original aragonite

Collected by MacDonald & Vaughan in 1911; reposited in the USNM

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

• COLLECTOR: D.F. MacDonald and T.W. Vaughan, 1911. REPOSITORY: USNM.
