Woodring Loc. 155c - eastern area [middle Gatun Fm] (Miocene of Panama)

Also known as USGS Loc. 16915

Where: Panama (9.3° N, 79.9° 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 Sr dating for nearby sections indicates an age of approximately 9.9 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

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

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

Size class: macrofossils

Reposited in the USNM

Collection methods: surface (in situ),

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