Also known as I41/f0162

Where: South Island, New Zealand (45.0° S, 170.7° E: paleocoordinates 51.2° S, 174.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Kokoamu Greensand Formation (Otiake Group), Duntroonian (27.3 - 25.2 Ma)

• yellow-green, highly glauconitic sandy limestone with sparse invertebrates and indistinct bedding, from just above/below the contact between the Kokoamu Greensand and Otekaike Limestone. The lithology is similar to that of a bone-rich shell bed also known as the ‘Lentipecten pavement’ [30] which has produced Carcharodon angustidens, Megalampris keyesi and Tokarahia kauaeroa [30–32] and which was dated using foraminifera and strontium isotopes as being 25.2 Mya, upper Duntroonian age (lower Chattian).

• bed-level stratigraphic resolution

Environment/lithology: marine; glauconitic, green, yellow, sandy limestone

Size class: macrofossils

Reposited in the OU

Collection methods: quarrying,
