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.
• bed-level stratigraphic resolution
Environment/lithology: lithified limestone
Size class: macrofossils
Preservation: cast, mold/impression
Collected by Reeds in 1915
