PPP# 227 - Cativa [lower Gatun Fm] (Miocene of Panama)

Also known as NMB Loc. 17645

Where: Colon, Panama (9.4° N, 79.8° W: paleocoordinates 9.1° N, 78.5° 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. BIOSTRATIGRAPHY: The Middle Gatun Fm is early Late Miocene (8.8-8.3 MA) according to Collins et al. (1999). Local section name: Sabanita to Payardi. AGE: Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 10.9 Ma (Hendy, unpublished data).

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified, bioturbated siltstone and unlithified, bioturbated siltstone

• ENVIRONMENT: from Collins et al. (1999), open, inner neritic.
• GENERAL LITHOLOGY: From Collins et al. (1999), the Middle Gatun Fm consists of alternating siltstone and sandstone with occasional 4-5 m units of interbedded sandstone and conglomerate. Pervasive bioturbation is extensive. LITHIFICATION: lithification data not reported, but assumed to be unlithified based on observation of specimens in Woodring (1957-1982).

Size class: macrofossils

Reposited in the NMB

Collection methods: bulk, sieve,

• COVERAGE: Exhaustive for gastropoda, bivalvia and scaphopoda. COLLECTORS: unknown (PPP staff) collected on 8/21/87. REPOSITORIES: Naturhistorisches Museum Basel (NMB),
