Coniacian/Santonian boundary in Riu de Carreu valley and Prats de Carreu, South-Central Pyrenees (N Spain)

open access: yes, 2002
A conspicuous level containing Platyceramus undulatoplicatus (Roemer) occurs in several stratigraphic profiles measured and sampled in a 15 km wide area along Riu de Carreu valley and Prats de Carreu. This is the index species for the Coniacian-Santonian

Timing and implications of Late Cretaceous tectonic and sedimentary events in Jamaica

open access: yesGeologica Acta, 2006
The Cretaceous succession in Jamaica can be divided into sedimentary packages bounded by major unconformities (synthems). On the base of biostratigraphy and ages derived from strontium isotope ratios, these unconformities have been dated as Early ...

A Santonian Campanian boundary locality from North western Turkey

open access: yes, 2015
A Santonian-Campanian boundary section, close to the village of Göynük in Northwestern Turkey (Bolu province), was recorded and examined in respect to nannofossil and foraminiferal biostratigraphy, magnetic susceptibility, as well as magnetic polarity ...

Changes in paleo-circulation and the distribution of ammonite faunas at the Coniacian–Santonian transition in central Poland and western Ukraine [PDF]

open access: yes, 2016
Ammonite distribution patterns and carbon and oxygen stable isotopes from the Lipnik-Kije (Poland) and Dubovcy (Ukraine) sections allow us to propose a model of sea water paleo-circulation in central Europe for the Coniacian-Santonian interval.

BIOSTRATIGRAPHIC STUDY OF THE ILAM AND GURPI FORMATIONS BASED ON PLANKTONIC FORAMINIFERA IN SE OF SHIRAZ, IRAN [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2002
The study of planktonic foraminifera of the Ilam and Gurpi formations at Sarvestan area (SE of Shiraz) enables me to find the most standard biozones defined in mediterranean regions, especially Tethysian domain. Seven biozones were determined. Biozones I

Volgian and Santonian–Campanian radiolarian events of the Russian Arctic and Pacific Rim [PDF]

open access: yes, 2012
Radiolarians are widely distributed in two siliceous intervals that coincide with the Tithonian–Berriasian and Santonian–Campanian boundaries in the Mesozoic of the Russian Arctic and Pacific Rim.
