Also known as NMB# 17632; 87-29-04

Where: Bocas, Panama (9.2° N, 82.1° W: paleocoordinates 9.1° N, 82.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Cayo Agua Formation (Bocas del Toro Group), Piacenzian (3.6 - 2.6 Ma)

• 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),
