Abstract
One hundred and five genera and subgenera and 201 species (65 siliceous and agglutinated species, 121 calcareous benthonic species, and 15 planktonic species) have been recorded in New Zealand Late Cretaceous (Haumurian) marine sediments. Micro-faunas obtained from Dunedin, North Otago, North Canterbury, Marlborough, southern Hawke's Bay, Raukumara Peninsula—East Coast, and Northland are incorporated in the present study. Three assemblage zones are recognised. The Trocham-mina globigeriniformis Zone contains only agglutinated taxa which are believed to be strongly facies-controlled and thus of limited use in correlation. The Rzehakina epigona Zone contains an entirely siliceous and agglutinated fauna which is closely comparable with Senonian-Eocene flysch microfaunas of the West European Alps and Polish Carpathians. The Globotruncana circumnodifer Zone contains rich assemblages of siliceous, agglutinated, and calcareous taxa. Certain elements present in this latter zone (= uppermost Haumurian) allow confident correlation with the Abathomphalus mayaroensis Range-zone of Trinidad and the Maastrichtian of Western Europe.
