Where: South Island, New Zealand (43.1° S, 172.6° E: paleocoordinates 56.4° S, 153.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Conway Formation, Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• The lithology was defined by Webb (1966) as the Laidmore Formation, a term also used in Welles and Gregg (1971). Later Warren and Speden (1978, p. 25) proposed that the Laidmore Formation be considered as a unit of the Conway Siltstone (Warren and Speden 1978); this was subsequently modified and published as the Conway Formation (Browne and Field 1985) and is now widely accepted as such (Wilson et al. 2005). The material was collected 6 m below the top of the Conway Formation. Wilson et al. (2005) extracted a sample from the matrix surrounding the holotype of P. waiparaensis and recorded a microflora dominated by taxa such as Manumiella seelandica (Lange, 1969), Manumiella druggii (Stover, 1973), Fibrocysta bipolaris (Cookson and Eisenack, 1965) and Alterbidinium longicornutum Roncaglia and Schiøler, 1997, an assemblage that confirms a late Maastrichtian age, close to the Cretaceous ⁄ Palaeogene boundary.
