Woodring Loc. 153a - Gatun Third Locks [middle Gatun Fm] (Miocene of Panama)

Also known as SU 2657; WG153a

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 Sr dating for nearby sections indicates an age of approximately 10.1 Ma (Hendy, unpublished data). STRATIGRAPHIC POSITION: Unit 3 of secton on p. 44.

• bed-level stratigraphic resolution

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

• No specific environmental data presented.
• LITHOLOGY: Fine sandstone.

Size class: macrofossils

Preservation: original aragonite

Collected by Thompson in 1942; reposited in the CAS

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

• COLLECTOR: T.F Thompson, 1942. REPOSITORY: Stanford Univeristy (CAS).
