Vaingana, Eua Island (Eocene of Tonga)

Where: Tonga (21.4° S, 174.9° W: paleocoordinates 31.1° S, 175.8° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Priabonian (38.0 - 33.9 Ma)

• No lithostratigraphic nomenclature for unit mentioned in 1970 or in later publications on Western Pacific Island Cenozoic strata (i.e. Ladd (1972, 1982). The collection is derived from a soft fossiliferous layer [unknown thickness] between two harder limestones. The exact extent of the richly fossiliferous bed is not known but is probably limited both horizontally and vertically. Eua is the oldest island in the Tonga island group that has a plutonic core and a series of volcanic rocks and sediments that are partly blanketed by thick limestones of late Eocene age. Younger volcanic rocks and sediments of late Tertiary age are also present.

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; poorly lithified, tuffaceous limestone

• Foraminifera suggest a depth of deposition of about 200 ft, but other groups, notably smaller forams, mollusks, ostracods, corals, brachiopods, barnacles, point to a considerably greater depth of deposition.
• Soft tuffaceous limestone.

Size class: macrofossils

Preservation: mold/impression

Reposited in the USNM

Collection methods: bulk, chemical,

• Derived from one 40-pound sample collected by Kondo [recent land snail taxonomist under orders to find locality and collect material] in 1967
