Where: North Otago, New Zealand (45.1° S, 170.9° E: paleocoordinates 52.4° S, 169.7° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Priabonian (38.0 - 33.9 Ma)
Environment/lithology: transition zone or lower shoreface; tuffaceous, volcaniclastic, calcareous conglomerate
•The mean-water depth of the Alma/Fortification Road rockground is estimated to be around 25 m
•moderately current-swept channel adjacent to small volcanic islands and seamounts
•"mobile rockground" of encrusted pebbles and cobbles in calcareous, tuffaceous volcanic conglomerate horizons
Size classes: macrofossils, mesofossils
Collection methods: chemical, sieve,
• Preparation: both encrusted clasts and iso1ated bryozoan fragments were soaked overnight in undiluted domestic bleach (NaOCl solution), following controlled sonication (usually several seconds), samples were thoroughly washed by gentle tumbling in clean water, then dried.
•Samples selected for study of agglutinated sediment particles were gently washed without bleaching or sonication.
