PPP# 1075 - Sabanita [lower Gatun Fm] (Miocene of Panama)

Also known as NMB Loc. 18322

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

• coordinate based on unpublished field data

• outcrop-level geographic resolution

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

• LITHOSRATIGRAPHY: From the Gatun Formation, for which lithostratigraphic relationships are not discussed. AGE: Late Miocene in text, earliest Tortonian on composite stratigraphic columns (e.g. Hendy 2013). STRATIGRAPHIC POSITION: From lower part of the Gatun Fm.

• bed-level stratigraphic resolution

Environment/lithology: shoreface; poorly lithified, bioturbated, fine-grained, silty sandstone

• Lithology is fine (typically silty) and often contains whole shells, but there is also shell hash that is sometimes packed into burrows, suggesting some wave energy. All faunal evidence suggests shallow conditions, less than 30-50 m, for most of the Gatun Formation. The area around Sabanita contains the shallowest-water faunas according to Hendy (2013), consistent with water depths <10 m.
• LITHOLOGY: Soft, silty fine-grained sandstone. LITHIFICATION: Poorly lithified, on the basis of observed specimens.

Size classes: macrofossils, mesofossils

Preservation: original aragonite

Collected in 1992; reposited in the NMB

Collection methods: bulk, surface (float), surface (in situ),

• COLLECTORS: 12/9/92. REPOSITORY: NMB.
