Where: Eua, Tonga (21.4° S, 174.9° W: paleocoordinates 31.1° S, 175.8° W)
• coordinate estimated from map
When: Priabonian (38.0 - 33.9 Ma)
• bed-level stratigraphic resolution
Environment/lithology: slope; lithified limestone and poorly lithified, tuffaceous limestone
Size classes: macrofossils, mesofossils
Preservation: original calcite
Collected by H.T. Stearns, Kondo, W. Bryan; reposited in the USNM
Collection methods: bulk, sieve,
• The soft tuffaceous limestones collected on Fua were treated with a wetting agent and penetrant in the laboratory. The material broke down easily, re- vealing a variety of fossil remains. The material is from two samples collected from approximately the same out- crop about one-quarter mile north of Vaingana, Eua, Tonga
