Geography
| Country: | Panama | State/province: | Colón |
| Coordinates: | 9.4° North, 79.9° West (view map) | ||
| Paleocoordinates: | 9.1° North, 78.5° West | ||
| Basis of coordinate: | based on nearby landmark | ||
| Geographic resolution: | small collection |
Time
| Period: | Neogene | Epoch: | Miocene |
| Stage: | Tortonian | 10 m.y. bin: | Cenozoic 6 |
| Key time interval: | Tortonian | ||
| Age range of interval: | 11.63 - 7.246 m.y. ago | ||
| Age estimate: | 11.1 Ma (other) |
Stratigraphy
| Formation: | Gatun | Member: | lower Gatun | ||
| Stratigraphy comments: 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 Sr dating for nearby sections indicates an age of approximately 11.1 Ma (Hendy, unpublished data). |
