PPP# 1995 - Swan Cay [Swan Cay Fm] (Pleistocene of Panama)

Also known as NMB Loc. 18372

Where: Bocas, Panama (9.5° N, 82.3° W: paleocoordinates 9.4° N, 82.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Swan Cay Formation (Bocas del Toro Group), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• No contacts are observed but the stratigraphic relationship of the Pleistocene Swan Cay formation is within the Bocas del Toro Group based on biostratigraphic data.

• bed-level stratigraphic resolution

Environment/lithology: marine; pebbly, volcaniclastic, silty, sandy sandstone

• The formation has three components. The lower 15m is exposed on the southernly low hill of the island and consists of silty sandstone and and shelly calcarenitic siltstone with coral rubble and red algal fragments and balls. The middle four m consists of calcarenitic clayey siltstone with dense, fine shell-hash horizons and abundant large coral colonies in the lower part. The upper 60m of the formation consists of massively thick-bedded pale tan-white calcarenite. The upper 30m are vuggy, sparry and clean and include a 4m thick coral bed with large Montastraea colonies and mollusks. The lower 30m consist of more silty calcarenite with common red algae and large foraminifera, shell hash and micromollusks. Cave deposits, about five m above the base of the calcarenite consist of silty, shelly, volcaniclastic sandstone, mixed with abundant volcanic cobbles and boulders and calcareous reef rubble containing and abundant and diverse molluscan assemblage.

Size class: macrofossils

Reposited in the BMNH, NMB, USNM

Collection methods: bulk, sieve,

• COVERAGE: Exhaustive for gastropoda, bivalvia and scaphopoda. COLLECTORS: unknown (PPP staff), 8/6/93. REPOSITORIES:collections presumably held at USNM, BMNH and Naturhistorisches Museum Basel (NMB),
