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 Sr dating for nearby sections indicates an age of approximately 11.1 Ma (Hendy, unpublished data).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