PPP# 376 Bruno Bluff [Shark Hole Fm] (Pliocene of Panama)

Also known as NMB Loc. 17850; 88-32-01

Where: Bocas, Panama (9.0° N, 81.7° W: paleocoordinates 9.3° N, 81.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: NN15 nannofossil zone, Shark Hole Point Formation (Bocas del Toro Group), Piacenzian (3.6 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: the Shark Hole Point Fm conformably overlies the Nancy Point Fm and is overlain by an unnamed sequence of volcaniclastics. BIOSTRATIGRAPHY: from Collins et al. (1999), an age range of 5.3-3.5 Ma, Early Pliocene, though PPP dataset indicates an age of 3.5-3.6 Ma corresponding to nannofossil stage NN15.

• bed-level stratigraphic resolution

• ENVIRONMENT: from Collins et al. 1999 (p. 94), outer neritic, estimated depth of 175 m.
• GENERAL LITHOLOGY: from Collins et al. 1999 (p. 28), micaceous, clayey siltstone that is pervasively bioturbated and rich in large scaphopods.

Size class: macrofossils

Reposited in the NMB

Collection methods: bulk, sieve,

• COVERAGE: Exhaustive for gastropoda, bivalvia and scaphopoda. COLLECTORS: unknown (PPP staff), 6/5/88. REPOSITORIES: Naturhistorisches Museum Basel (NMB),
