Station 105 - Eua [Nautiloidea] (Miocene to of Tonga)

Where: Tonga (21.4° S, 175.9° W: paleocoordinates 27.6° S, 176.0° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Early/Lower Miocene to Early/Lower Miocene (23.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From unnamed lithostratigraphic unit, comprising volcanic tuff, which overlies Eocene limestone. AGE: ?Miocene according to Hoffmeister (1932) and Miller (1941) on the basis of foraminiferal biostratigraphy and morphology of specimen. More likely to be Early or Middle Miocene if Aturia aturi or close relative. STRATIGRAPHIC POSITION: From unknown position with lithostratigraphic unit.

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, volcaniclastic, calcareous tuff

• ENVIRONMENT: Not stated in text, but probably shallow siliciclastic marine environment.
• LITHOLOGY: Soft horizontally bedded volcanic tuff. LITHIFICATION: Poorly lithified, on the basis of figured specimen and facies description

Size class: macrofossils

Collected by Hoffmeister

Collection methods: surface (in situ),
