| 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: | 11.5 Ma (other) |
| Formation: | Gatun |
Member: | lower Gatun |
| Stratigraphic resolution: | bed |
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Gatun Fm, which regionally overlies the Caimito Fm or Mesozoic basement. 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 Sr dating for nearby sections indicates an age of approximately 11.5 Ma (Hendy, unpublished data). STRATIGRAPHIC POSITION: From unknown position within formation. |
