GS10489, Gore Bay Road (O33/f8047) (Cretaceous of New Zealand)

Where: Cheviot, New Zealand (42.9° S, 173.3° E: paleocoordinates 56.5° S, 152.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Maastrichtian (72.1 - 66.0 Ma)

• All specimens were collected from a horizon thought to be Late Cretaceous, Haumurian (=Maastrichtian) in age. The specimens taken from the first four localities listed above were taken from a 7.5 cm thick layer of phosphatic nodules and occasional macrofossils in a matrix of soft sand about 70 m above the base of Late Cretaceous sands. This faunule is consistent with a late Piripauan-Haumurian (Campanian-Maastrichtian) age. However, similar macrofossils are present, though rare, in the immediately underlying sands, suggesting that the horizon bearing the decapods and the above-listed suite is a lag concentration resulting from erosion of a considerable thickness of sediment. A microfossil sample from 2 m above the phosphatic band is of Teurian (Paleocene) age, which suggests that the lag accumulated at, or near, the end of the Cretaceous, presumably during a brief regressive phase.

Environment/lithology: marine; nodular, phosphatic sandstone

Size class: macrofossils
