Woodring Loc. 177b - Mount Hope [upper Gatun Fm] (Miocene of Panama)

Also known as USGS 5854; WG177b

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 Sr dating for nearby sections indicates an age of approximately 9.5 Ma (Hendy, unpublished data).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

• No specific environmental data presented.
• LITHOLOGY: Siltstone.

Size class: macrofossils

Preservation: original aragonite

Collected by D.F. MacDonald in 1911; reposited in the USNM

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

• COLLECTOR: MacDonald. REPOSITORY: USNM.
