Time
Period:Neogene Epoch:Miocene
Stage:Tortonian 10 m.y. bin:Cenozoic 6
Key time interval:Tortonian
Age range of interval:11.63000 - 7.24600 m.y. ago

Stratigraphy
Formation:Gatun Member:upper Gatun
Stratigraphic resolution:bed
Stratigraphy comments: Upper 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: 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 Sr dating for nearby sections indicates an age of approximately 8.5 Ma (Hendy, unpublished data).
