S3, South Mathesons Bay (R09/f132, L17562) (Miocene of New Zealand)

Where: New Zealand (36.3° S, 174.8° E: paleocoordinates 44.9° S, 177.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Waitemata Group, Aquitanian (23.0 - 20.4 Ma)

• Early Otaian

Environment/lithology: shoreface; lithified, pebbly sandstone and conglomerate

• 0-10 m of fossiliferous pebbly sandstone and sandy pebble conglomerate (sandstone-conglomerate facies of Ricketts et al. 1989). This latter unit has variably developed stratification often with wedge-shaped conglomerate beds. Pebble- and sand-filled subcylindrical excavations, up to 0.3 m diameter and depth (ray-feeding burrows, Gregory 1991), are plentiful along the bases of some beds. This thick unit grades laterally northwards into a coarser facies of shelly, subrounded to subangular pebble breccia adjacent to the paleostack

Size classes: macrofossils, mesofossils, microfossils
