Correlation of Early Cretaceous carbon isotope stratigraphy and platform drowning events: a possible link?
The Early Cretaceous carbonate carbon isotope record is marked by three positive high-amplitude (> 1.5‰) excursions each covering time spans of more than 106 years. They are of lateExpand

Volcanism, CO2 and palaeoclimate: a Late Jurassic–Early Cretaceous carbon and oxygen isotope record
A composite Tethyan Late Jurassic–Early Cretaceous carbon and oxygen isotope curve is presented. C-isotope data provide information on the evolution and perturbation of the global carbon cycle.Expand

Phosphogenesis, carbon-isotope stratigraphy, and carbonate-platform evolution along the Lower Cretaceous northern Tethyan margin
We distinguish three different stages in the evolution of the Tithonian (Late Jurassic) to Aptian (Early Cretaceous) northern Tethyan carbonate platform: (1) carbonate production in the coral-ooliteExpand

The Valanginian carbon isotope event: a first episode of greenhouse climate conditions during the Cretaceous
Lower Cretaceous pelagic carbonates outcropping along the Southern Alps of northern Italy provide a record of Tethyan palaeoceanography as well as of low frequency fluctuations in the global carbonExpand

Timing of the Early Triassic carbon cycle perturbations inferred from new U–Pb ages and ammonoid biochronozones.
Based on analyses of single, thermally annealed and chemically abraded zircons, a new high-precision U–Pb age of 251.22± 0.20 Ma is established for a volcanic ash layer within the “KashmiritesExpand

Response of Early Cretaceous carbonate platforms to changes in atmospheric carbon dioxide levels
During the Late Barremian and Early Aptian (about 120 million years ago) intense volcanic degassing and extremely rapid release of methane hydrates contained in marine sediments added high amounts ofExpand

Late Jurassic climate and its impact on carbon cycling
Abstract The climate of the Late Jurassic has been characterized by high atmospheric CO2 levels and by a monsoonal rainfall pattern. In this study we traced the evolution of the global carbon cycleExpand

Timing of early angiosperm radiation: recalibrating the classical succession
New stratigraphically controlled pollen data from the late Early Cretaceous of Portugal allow a recalibration of the classical continental succession of the Potomac Group (USA), which has long beenExpand

Anomalies in global carbon cycling and extinction at the Triassic/Jurassic boundary: evidence from a marine C-isotope record
This study investigates whether the end-Triassic biotic crisis was coupled with a perturbation of the marine C-isotope budget. The marine C-isotope signature serves as a proxy of the marine carbonExpand
