Also known as NMB Loc. 17854

Where: Bocas, Panama (9.1° N, 81.8° W: paleocoordinates 9.5° N, 81.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: NN15 nannofossil zone, Shark Hole Point Formation (Bocas del Toro Group), Zanclean (5.3 - 3.6 Ma)

• LITHOSTRATIGRAPHY: the Shark Hole Point Fm conformably overlies the Nancy Point Fm and is overlain by an unnamed sequence of volcaniclastics. AGE: 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/lithology: offshore; poorly lithified, bioturbated, micaceous, shelly/skeletal, argillaceous siltstone

• 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.
