Also known as Woodring Loc. 147a; WG147a
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 Sr dating for nearby sections indicates an age of approximately 10.1 Ma (Hendy, unpublished data).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; unlithified, fine-grained, silty sandstone
Size class: macrofossils
Preservation: original aragonite
Collected by D.F. MacDonald, T.W. 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.
