Stratigraphy
| Formation: | Gatun | Member: | middle Gatun | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Middle part of the Gatun Formation. The Gatun Formation is sibdivided into three faunal zones (proposed by Thomson and Keen, 1946): lower, middle, and upper. AGE: Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 10.5 Ma (Hendy, unpublished data). | |||||
