Couper, R.A. 1960 New Zealand Mesozoic and Cainozoic plant microfossils. Government Print: Wellington. New Zealand Geological Survey paleontological bulletin 32 87 p.

Abstract: In Part 1, the stratigraphic distribution of fossil spores and pollen grains from numerous localities is discussed. The establishment of ranges of species and the correlation of Upper Cretaceous and Tertiary freshwater deposits with the New Zealand marine stages was aided by study of spore and pollen floras from some of the standard marine sections. A summary of Cretaceous and Cainozoic vegetational changes and a tentative correlation with climatic changes is given. The occurrence of microplankton (mainly hystrichosphaerids) in some samples is briefly notes. In Part 2, 139 species, including three new genera and 40 new species, are systematically described and illustrated. Some are of limited stratigraphic value at present but are included because of their botanical interest. Many of the others will almost certainly become key species in New Zealand Upper Cretaceous and Cainozoic stratigraphy. (auth)
