Where: Puerto Rico (18.5° N, 67.0° W: paleocoordinates 18.4° N, 65.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Quebradillas Limestone Formation, Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Quebradillas Limestone, which regionally overlie the Ponce chalky beds [subsequently referred to as Ponce Fm], and is laterally related to the Oak Grove Sands (Florida). AGE: Early-Middle Miocene based on macro- and microfaunal biostratigraphy in text. Here assigned to Middle Miocene based on more recent dating. STRATIGRAPHIC POSITION: From unknown position within formation.
