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]

open access: yes, 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.

Lithostratigraphy and biostratigraphy of the upper cretaceous succession of Southeastern Sinai, Egypt

open access: yesEgyptian Journal of Petroleum, 2011
The calcareous nannofossil of the Upper Cretaceous successions exposed at Taba and El sheikh Attia sections at Southeastern Sinai in Egypt have been studied to contribute in the understanding of lithostratigraphy and biostratigraphy.

Integrated stratigraphy of the Upper Barremian–Aptian sediments from the south-eastern Crimea

open access: yesGeologica Carpathica, 2018
Previous studies made in different parts of the world have shown that Barremian–Aptian times imply many difficulties in deciphering the biostratigraphy, microfossil evolution and correlation of bioevents.

Biostratigrafie spodní křídy manínské jednotky (lom Butkov, Strážovské vrchy, Západní Karpaty) [PDF]

open access: yes, 2003
This paper is a continuation of systematic stratigraphical research of Lower Cretaceous sequence of the Manín Unit excavated in the Butkov quarry. Calcareous deposits are significant especially by richness of ammonites.
