When: Kokoamu Greensand Formation, Duntroonian (27.3 - 25.2 Ma)
Environment/lithology: marine; lithified, bioturbated, brown, green sandstone and lithified, glauconitic, brown, yellow limestone
•Marl Member of the McDonald Limestone, with a complex burrow and cavity system below (Lewis & Bellis 1984, fig. 9). The lower 2-3 m section of Kokoamu Greensand is intensely bioturbated and consists mainly of silt and fine sand-sized grains with >50% glauconite (Fig. 2). Macrofossils are rare in
•the lower part but are abundant in the upper 0.5-1.0 m of the Kokoamu, which is a fine-grained, greenish brown, calcareous greensand that grades upward into the glauconitic, yellowish brown Otekaike Limestone.
Size classes: macrofossils, mesofossils
Collection methods: sieve,
