Also known as NMB Loc. 17641

Where: Colon, Panama (9.4° N, 79.8° W: paleocoordinates 9.1° N, 78.4° W)

• coordinate stated in text

• outcrop-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. Locality: Sabanita to Payardi. AGE: Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 11.3 Ma (Hendy, unpublished data).
