Cativá [lower Gatun Fm] (Miocene of Panama)

Where: Colón, Panama (9.4° N, 79.9° W: paleocoordinates 9.1° N, 78.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: lower Gatun Member (Gatun Formation), Tortonian (11.6 - 7.2 Ma)

• lower 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 Sr dating for nearby sections indicates an age of approximately 11.1 Ma (Hendy, unpublished data).

Environment/lithology: marine; marl

Size class: microfossils

Collected by J. Embich in 1934; reposited in the AMNH
