PRI Pitt Loc. 96 - Sabanita [lower Gatun Fm] (Miocene of Panama)

Also known as GA-11

Where: Panama (9.3° N, 79.8° W: paleocoordinates 9.1° N, 78.4° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: lower Gatun Member (Gatun Formation), Tortonian (11.6 - 7.2 Ma)

• STRATIGRAPHIC RELATIONS: The Gatun Fm rests unconformably on formations of different ages in different parts of the Panama Canal Basin. To the east of Colon, the Gatun Fm rests nonconformably on unamed Cretaceous volcanics. To the west of Colon, including several islands in Lake Gatun, the Gatun Fm rests with angular unconformity on the upper Oligocene Caimito Fm. AGE: Late Miocene, on the basis of microfossil biostratigraphy (see Collins and Coates, 1999). AGE: Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 11.5 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified, fine-grained, brown, gray, green sandstone

• ENVIRONMENT: from Collins et al. (1999), open, inner neritic.
• LITHOLOGY: Not recorded, but certainly silciclastic. LITHIFICATION: Unlithified, on the basis of observation of specimens.

Size class: macrofossils
