Planktonic Foraminiferal Zones and New Taxa From the Lower Miocene to the Pleistocene of New Zealand

Abstract

The stratigraphic ranges of 80 species and subspecies of planktonic Foraminifera from the Pareora Series (Lower Miocene) to the Hawera Series (Upper Pleistocene) of New Zealand have been determined. A biostratigraphical zonal scheme based on these ranges is given, and the eight zones are defined and discussed in relation to the New Zealand Stages. A correlation is made with the planktonic foraminiferal zones established in Trinidad, based on the stratigraphic ranges of five important species common to both areas. The following new planktonic Foraminifera are described and illustrated from the New Zealand Lower to Upper Miocene rocks: Globorotalia bella, Globorotalia mayeri nympha, Globorotalia miotumida explicationis, and Globorotalia nana pseudocontinuo sa. © 1967 Taylor & Francis Group, LLC.
