Isotopic evidence for Late Jurassic-Early Cretaceous climate change
Abstract Strontium-, oxygen- and carbon-isotope ratios have been determined from Late Jurassic–Early Cretaceous belemnites from the Volga Basin, Russia, and Kawhia Harbour, New Zealand. 87Sr/86SrExpand

The Cenomanian - Turonian of the Wunstorf section - (North Germany): global stratigraphic reference section and new orbital time scale for Oceanic Anoxic Event 2
The Cenomanian–Turonian Boundary Event (CTBE) is reflected by one of the most extreme carbon cycle perturbations in Earth's history and is characterized by the widespread occurrence of sedimentsExpand

Stable organic carbon isotope stratigraphy across Oceanic Anoxic Event 2 of Demerara Rise, western tropical Atlantic
Ocean Drilling Program (ODP) Leg 207 recovered expanded sections of organic-carbon-rich laminated shales on Demerara Rise (western tropical Atlantic). High-resolution organic carbon isotope and totalExpand

Stable isotope records from Sepia officinalis—a key to understanding the ecology of belemnites?
Abstract The stable isotope ratios (δ 1 8 O, δ 1 3 C) of the aragonite of cuttlebones of Sepia officinalis were measured on a high resolution scale where every septum was measured. Our studies aim atExpand

Isotopic signals from late Jurassic–early Cretaceous (Volgian–Valanginian) sub-Arctic belemnites, Yatria River, Western Siberia
This contribution presents the first detailed oxygen and carbon isotope record from the latest Jurassic–early Cretaceous interval of the Yatria River, subpolar Urals, Siberia. Isotopic compositionsExpand

The impact of calcareous nannofossils on the pelagic carbonate accumulation across the Jurassic–Cretaceous boundary
Abstract Calcareous nannofossils were important producers of pelagic carbonates in Mesozoic oceans. In order to better understand the origin of Mesozoic pelagic carbonates we studied upper JurassicExpand

Calcareous nannofossils of the Cenomanian/Turonian boundary interval from the Boreal Realm (Wunstorf, northwest Germany)
Abstract The Cenomanian/Turonian boundary interval (CTBI) is marked by an intense climatic warming presumably caused by large magmatic eruptions. This warming was characterised by one of the mostExpand

U–Pb and Re–Os geochronology of the Aptian/Albian and Cenomanian/Turonian stage boundaries: Implications for timescale calibration, osmium isotope seawater composition and Re–Os systematics in
Abstract Presented is the first absolute age for the basal Albian from the Schwicheldt Ton Member, Gault Formation, Vohrum, Germany. A 206 Pb/ 238 U age of 113.1 ± 0.3 Ma is determined for chemicallyExpand

Distribution and facies patterns of Lower Cretaceous sediments in northern Germany: a review
Marine sediments of Early Cretaceous age (Berriasian–Albian) have a widespread distribution in the Lower Saxony Basin of northern Germany. This basin, which is about 400 km long and 100 km wide,Expand

Calcareous nannofossils from the Paleocene-Eocene Thermal Maximum of the equatorial Atlantic (ODP Site 1260B): Evidence for tropical warming
Abstract Independent geological and micropaleontological lines of evidence suggest a ∼ 200 kyr, period of intense warming covering the Paleocene/Eocene boundary interval (PETM). It has been suggestedExpand
