• 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 NN16; also contains the planktonic foraminifers Globorotalia pseudomiocenica. STRATIGRAPHIC POSITION: At a height of 2 m in section 19 of Coates & Collins (1999).

• bed-level stratigraphic resolution

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

•LITHIFICATION: Not stated in text, but known to be poorly lithified by enterer; figured specimens appear to have been cleaned of sediment.
