Also known as NZGS coll. 753

Where: Central Otago, New Zealand (45.0° S, 170.2° E: paleocoordinates 51.2° S, 175.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Naseby Greensand Formation (Stranraer Group), Late/Upper Oligocene (28.4 - 23.0 Ma)

• Originally listed as "Greensands". Described in text as from units of the Naseby Series (now Naseby Greensand), part of the Pareora Formation of Hutton (1875). From Bishop (1979): Naseby Greensand (Stranraer Group) is approximatey 250-300 m thick, underlain by metamorphosed schist or siltstone of the Eocene Swinburn Formation (Stranraer Group), and overlain conformably by current-bedded quartz sands and gravels of the late Oligocene/early Miocene Wedderburn Formation (Stranraer Group).

•Bishop, D.G. 1979: Sheet 135, Ranfurly (1st ed.) "Geological Map of New Zealand 1:63 360". N.Z. Dept. Sci. Ind. Res., Wellington

Environment/lithology: coastal; poorly lithified, coarse-grained, green sandstone

Size class: macrofossils

Collection methods: quarrying,

• Collected by J. Hector, 1890. Williamson (1939) does discuss possibility of some mixing in this collection, between either multiple horizons, or multiple locations
