Where: Northern Mariana Islands (15.0° N, 145.6° E: paleocoordinates 15.0° N, 146.3° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Mariana Limestone Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)

AGE: Early Pliocene on the basis of foraminiferal biostratigraphy. STRATIGRAPHIC POSITION: Composite list undifferentiated Mariana Limestone equivalent localities.
• formation-level stratigraphic resolution
Environment/lithology: lithified limestone
Size class: macrofossils
