Also known as Stanford University Loc. 2672
Where: Panama (9.3° N, 79.9° W: paleocoordinates 9.1° N, 78.5° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: upper Gatun Member (Gatun Formation), Tortonian (11.6 - 7.2 Ma)
• 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 Sr dating for nearby sections indicates an age of approximately 9.5 Ma (Hendy, unpublished data).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: coastal; poorly lithified, fine-grained, silty sandstone
Size class: macrofossils
Preservation: original aragonite
Collected by Thompson in 1943; reposited in the CAS
Collection methods: surface (in situ),
• COLLECTOR: F. Thompson, 1943. REPOSITORY: Stanford University (now at CAS ?).
