Woodring Loc. 157 - Gatun Third Locks [middle Gatun Fm] (Miocene of Panama)

Also known as USGS 16926; WG157

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 Sr dating for nearby sections indicates an age of approximately 10.1 Ma (Hendy, unpublished data).

• 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 Woodring in 1947; reposited in the USNM
