Standard Palaeogene Calcareous Nannoplankton Zonation
Nature, 1970THE stratigraphic value of a group of marine minute algae usually referred to as the calcareous nannoplankton, first shown by Bramlette and Riedel1, has already been discussed2. A standard zonation, based partly on the investigations of Hay et al.3 and Bramlette and Wilcoxon4, has been proposed, and the Neogene calcareous nannoplankton zones have been ...

Abstract A comprehensive nannoplankton biozonation of the Pliocene-Pleistocene succession of off-shore Nile Delta has been recorded from two wells, namely Baltim-1 and NDOB-1, in the present contribution. The biozonation is relied the identification of 8 nannoplankton biozones and their associated bioevents.

Nature, 1953
ATKINS1, in 1945, reported on the productivity of the English Channel as estimated by two independent methods. The silicate turnover indicated a far lower productivity than did the phosphate turnover, and from this he deduced that only a relatively small fraction of the phytoplankton could consist of forms with siliceous skeletons.

Notes for a Short Course: Studies in Geology, 1987
Calcareous nannoplankton are minute plant-like protists that live in the marine photic zone. There has been an exponential increase in nannoplankton studies in the last two decades, largely owing to the recognition of the usefulness of this group for biostratigraphic and paleoenvironmental interpretations.

Taxon lists for studies of modern nannoplankton
Marine Micropaleontology, 2000Six studies in this special issue dealt with modern nannoplankton assemblages. In total during these studies 552 samples were analysed and about 180,000 specimens identified, from 152 species. This paper provides a unified list of taxa from these studies, records the presence/absence of each species across the studies and indicates the more common ...

Late Maastrichtian Nannoplankton Provinces
Nature, 1970IT has been known for some time that there was a sharp differentiation of late Maastrichtian faunal provinces with respect to planktonic foraminifera. Axelrod1 has presented evidence that this was also the case with some terrestrial megaphyta, for he found a rather abrupt southward shift for the coniferous vegetation of the northern hemisphere during ...

Annotated index and bibliography of the calcareous nannoplankton V
Phycologia, 1966Abstract This annotated index of 581 entries includes modern and fossil calcareous nannoplankton taxa of all levels, in addition to those appearing in the earlier index and supplements. Some 320 are new entries, 198 of which are valid and 122 invalid.

Calcareous Nannoplankton from the Tertiary of Alabama
Micropaleontology, 1967Three biostratigraphic units are recognized on the basis of the vertical distribution of coccolithophorids and related calcareous nannofossils from the Upper Eocene, Lower Oligocene and Middle Oligocene of exposures at Little Stave Creek and St. Stephens Quarry, Alabama.
