Also known as NMB Loc. 18771

Where: Bocas del Toro, Panama (9.1° N, 82.0° W: paleocoordinates 9.0° N, 81.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: NN11 nannofossil zone, Nancy Point Formation (Bocas del Toro Group), Messinian (7.2 - 5.3 Ma)

• LITHOSTRATIGRAPHY: Nancy Point Fm is conformable with the Tobabe Fm below and the Shark Hole Point Fm above. AGE: from Collins et al. (1999), an age range of 8.2-5.6 Ma, Late Miocene, though PPP dataset indicates an age of 6.5-5.6 Ma; NN11 (Discoaster quinqueramus); also contains planktonic foraminifers Globigerinoides conglobatus, Globorotalia plesiotumida, and Globigerinoides seigliei. STRATIGRAPHIC POSITION: From silts with concretions, about 25°W dipping; rich in molluscs, scattered; 51.75 m in section 14 of Coates & Collins (1999).

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, concretionary siltstone

• LITHOLOGY: Silts with concretions, about 25°W dipping; rich in molluscs, scattered. LITHIFICATION: Not stated in text, but known to be poorly lithified by enterer; figured specimens appear to have been cleaned of sediment.

Size class: macrofossils
