Also known as NMB Loc. 18734

Where: Bocas del Toro, Panama (9.1° N, 82.0° W: paleocoordinates 9.1° N, 81.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: NN12-15 nannofossil zone, Cayo Agua Formation (Bocas del Toro Group), Piacenzian (3.6 - 2.6 Ma)

• LITHOSTRATIGRAPHY: From the Cayo Agua Formation, which 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. AGE: Early Pliocene (Zanclean) in text; Nannoplankton zone NN12-15; also contains the planktonic foraminifers Globorotalia pseudomiocenica. STRATIGRAPHIC POSITION: At a height of 2 m in section 17 of Coates & Collins (1999).

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, bioturbated, shelly/skeletal, gray, blue, silty sandstone

• 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.

•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
