Key species of New Zealand calcareous nannofossils

New Zealand Journal of Geology and Geophysics, 1973
Abstract A genus, Hornibrookina, and three species, Conococcolithus panis, Hornibrookina teuriensis and Reticulofenestra hampdenensis, are described as new from the New Zealand Paleogene; an existing genus, Reticulofenestra, is redefined. Several technical terms are introduced and a new tentative suprageneric classification of the Cenozoic calcareous ...

Calcareous Nannofossil Studies--State of Art: ABSTRACT

AAPG Bulletin, 1973
Nannofossils commonly occur in astronomically large numbers in fine-grained marine deposits. This fact, coupled with the rapid evolution that characterizes the group and the succession of distinctive assemblages, makes them extremely useful for dating Mesozoic and Cenozoic marine strata.

Calcareous nannofossil biostratigraphy of the California margin

2000
Selected calcareous nannofossils were investigated by means of quantitative and semiquantitative methods in middle Miocene to Pleistocene sediments from the California margin (Pacific Ocean) recovered during Ocean Drilling Program Leg 167. The goal of the work was to provide detailed dating and correlations of the successions recovered that span a wide
