(by N. de B. Hornibrook) : At most places, including the type locality, the Piripauan is composed of well sorted medium sandstone that is devoid of useful microfossils. A microfauna has recently been collected from George Stream, a tributary of Mangaotane River, in the Raukumara Peninsula, with Inoceramus pacificus (GS6275). It contains the following species: Bathysiphon sp., Rhabdammina sp., Proteonina, 2 spp., Ammodiscus glabratus Cushman and Jarvis. Glomospira corona Cushman and Jarvis, Gaudryinella sp., Marssonella aff. oxycona (Reuss), Haplophragmoides 2 spp., Lagenidae, Gyroidina aff. nitida (Reuss), G. aff. globosa (Hagenow), Cibicides sp., Globigerina aff. cretacea d'Orb., abundant, and Globigerinella aff. aspera (Ehrenberg). The Cibicides sp. and Gaudryinella sp. occur in the Puketoro and Mangaotane mudstones—part of the Raukumara Series of Wellman (1955)—but are not known in the Haumurian. Globigerina aff. cretacea is usually abundant in the Clarence and Raukumara series but is not known in the Haumurian or Teurian stages. The Piripauan microfaunas thus more closely resemble those of the Raukumara Series than they do those of the Haumurian Stage. Teratan Stage (lower Campanian) Type Locality (Fig. 11). The Teratan is the uppermost stage of the Raukumara Series. It is defined as the beds with Inoceramus nukeus and I. opetius at the Mangaotane Valley section. The name is taken from Te Rata Stream, a tributary of Mangaotane River. The beds consist of massive blue-grey siltstone and are about 1,000ft
