Where: Palau (7.4° N, 134.6° E: paleocoordinates 7.4° N, 134.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Palau Limestone Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• STRATIGRAPHIC RELATIONS: From the Palau Limestone, which unconformably overlies the Ngeremlengui Fm (Oligocene) and is overlain by the Peleliu Fm. AGE: Late Miocene on the basis of foraminiferal biostratigraphy. STRATIGRAPHIC POSITION: From base of Palau Limestone.

Environment/lithology: shallow subtidal; unlithified, tuffaceous marl

• ENVIRONMENT: Shallow subtidal carbonate facies.
• SPECIFIC LITHOLOGY: Tuffaceous marl facies. LITHIFICATION: Unlithified, not stated, but based on figured specimens.

Size class: macrofossils
