Also known as NMB Loc. 17620
Where: Panama (9.0° N, 80.6° W: paleocoordinates 9.2° N, 79.3° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: 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. BIOSTRATIGRAPHY: From unknown member of Gatun Fm, but most of the Gatun is Late Miocene (12.0-7.9 MY) according to Collins et al. (1999).
• bed-level stratigraphic resolution
Environment/lithology: coastal; unlithified lithology not reported
Size class: macrofossils

• COVERAGE: Exhaustive for gastropoda, bivalvia and scaphopoda. COLLECTORS: unknown (PPP staff), 8/5/87. REPOSITORIES:collections presumably held at USNM, BMNH and Naturhistorisches Museum Basel (NMB),
