Stratigraphy of Cretaceous to Lower Pliocene sediments in the northern part of Cyprus based on comparative 87Sr/86Sr isotopic, nannofossil and planktonic foraminiferal dating [PDF]

, 2012
New age data from Sr isotope analysis and both planktonic foraminifera and nannofossils are presented and discussed here for the Upper Eocene–Upper Miocene sedimentary rocks of the Değirmenlik (Kythrea) Group.

Developing a new species-level database of Cretaceous calcareous nannoplankton occurrences – Uneptune [PDF]

Journal of Micropalaeontology
Calcareous nannofossils are abundant and globally distributed fossils that are widely used in the study of stratigraphy and palaeoclimate. A large number of nannofossil data have been generated over the past several decades, but the information is ...
