Station 110B [Ndalithoni Limestone] (Pliocene of Fiji)

Where: Fiji (17.2° S, 179.0° E: paleocoordinates 19.2° S, 178.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Ndalithoni Limestone Formation, Pliocene (5.3 - 2.6 Ma)

• STRATIGRAPHIC RELATIONS: From Ndalithoni Limestone, which overlies the Koro Mbasanga volcanics (?Late Miocene) and is overlain by Recent alluvium and beach sands. AGE: Pliocene according to Ladd (1945), and stage "h" of Van der Vlerk. Assigned to a Pliocene age, although Ladd's assignment is founded on lyelian percentages. STRATIGRAPHIC POSITION: Unknown position within unit.

• bed-level stratigraphic resolution

Environment/lithology: poorly lithified, shelly/skeletal, calcareous conglomerate

• ENVIRONMENT: Unknown environment, though presumably shallow water carbonate.
• SPECIFIC LITHOLOGY: Conglomerate. Otherwise unknown lithology, though from limestone unit. LITHIFICATION: Presumed poorly lithified, given young age and extreme diversity relative to other underlying limestone units.

Size class: macrofossils

Collection methods: COLLECTOR: H.S. Ladd and E.J. Hoffmeister, presumably with others. REPOSITORY: Unknown, possibly the Bernice P. Bishop Museum, Honolulu, Hawaii, or the USNM.
