THE DEMISE OF THE MESSINIAN SALINITY CRISIS AND THE BEGINNING OF THE ZANCLEAN IN THE NORTHERN MEDITERRANEAN BASIN: INSIGHT FROM HIGH-RESOLUTION BIOMAGNETOSTRATIGRAPHY (POLLENZO SECTION, NW ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia
The Messinian-Zanclean boundary in the Mediterranean basin marks the end of the Messinian salinity crisis (MSC) at approximately 5.33 Ma. The mechanism behind the return to normal marine conditions after the MSC are debated, with two main hypotheses ...

Calcareous nannoplankton evolution and the Paleogene greenhouse to icehouse climate-mode transition [PDF]

open access: yes, 2017
This thesis addresses calcareous nannoplankton evolutionary and palaeoecological response across the Paleogene greenhouse to icehouse transition using newly drilled material from Sites U1408 and U1411 (IODP Expedition 342) in the North Atlantic ...

Calcareous Nannoplankton and Problematic Microorganisms Found in the Late Palaeozonic Limestones [PDF]

open access: yes, 1979
Two species of calcareous nannoplankton belonging to genus Thoracosphaera found in the Upper Pennsylvanian limestones of Kansas, U.S.A., are systematically described. Two other calcareous microorganisms of uncertain afinity are also described.

Lineages in early paleogene calcareous nannoplankton

open access: yes, 1979
A detailed study of the ultrastructure of Paleocene-Middle Eocene calcareous nannofossils has led to the recognition of evolutionary lineages comprising 16 genera and 110 species. The lineages have been established on the basis of evidence from floras derived from closely sampled sections in Spain, Israel, Denmark and Sweden.

Planktonic ecosystems of the Upper Jurassic and Cretaceous (calcareous nannoplankton, calpionellids) [PDF]

open access: yes, 2016
The presented PhD thesis is compiled as a commentary to four published papers, which deal with planktonic assamblages of the Upper Jurassic and Cretaceous, namely with calcareous nannofossils and calpionellids.

Middle Tertiary Calcareous Nannoplankton of the Cipero Section, Trinidad, W. I.

open access: yes, 2017
The middle Tertiary calcareous nannoplankton in the Cipero section of Trinidad are described, and their distribution in the samples from the foraminiferal zones of Bolli shown. From these data a zonation based on the calcareous nannoplankton is indicated.
