PPP# 201 - Cayo Agua [Cayo Agua Fm] (Pliocene of Panama)

Also known as NMB# 17635

Where: Bocas del Toro, Panama (9.2° N, 82.0° W: paleocoordinates 9.1° N, 81.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Cayo Agua Formation (Bocas del Toro Group), Zanclean (5.3 - 3.6 Ma)

• STRATIGRAPHIC RELATIONS: the Cayo Agua Fm is equivalent in age to the upper part of the Shark Hole Point Fm and the lower part of the Escudo de Veraguas Fm, no contacts are known. BIOSTRATIGRAPHY: from Collins et al. (1999), no specific ages listed, but assumed to be similar to preceding and locally neighboring collections; direct date from Cheetham et al. (1999).

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; poorly lithified, bioturbated, shelly/skeletal, gray, blue, argillaceous, silty sandstone

• ENVIRONMENT: from Collins et al. 1999 (p. 94), open inner neritic, estimated depth of 30 m.
• GENERAL LITHOLOGY: from Collins et al. 1999 (p. 29), pervasively bioturbated gray blue, muddy, silty, lithic sandstone with comon horizons of abundant thick shelled mollusks and ahermatypic corals.

Size class: macrofossils

Preservation: original calcite

Reposited in the BMNH, NMB, USNM

Collection methods: bulk, sieve,

• COVERAGE: Exhaustive for gastropoda, bivalvia and scaphopoda. COLLECTORS: unknown (PPP staff), 8/11/87. REPOSITORIES:collections presumably held at USNM, BMNH and Naturhistorisches Museum Basel (NMB),
