It is well established that greenhouse conditions prevailed during the Cretaceous Period (~
145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming …

Although the axial and dominant geocentric character of the Earth's magnetic field means
that paleolongitude is indeterminate, paleomagnetism is otherwise the only truly quantitative …

Dissolved oxygen (O2) is essential for most ocean ecosystems, fuelling organisms'
respiration and facilitating the cycling of carbon and nutrients. Oxygen measurements have …

Abstract The Eocene–Oligocene transition (EOT) was a climate shift from a largely ice-free
greenhouse world to an icehouse climate, involving the first major glaciation of Antarctica …

The determinants of biodiversity patterns can be understood using macroevolutionary
analyses. The integration of fossils into phylogenies offers a deeper understanding of …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

This contribution provides an overview of Paleomagnetism. org, an open-source, multi-
platform online environment for paleomagnetic data analysis. Paleomagnetism. org provides …

Abstract The Late Cretaceous–Early Paleogene is the most recent period in Earth history
that experienced sustained global greenhouse warmth on multimillion year timescales. Yet …

Past greenhouse periods with elevated atmospheric CO2 were characterized by globally
warmer sea-surface temperatures (SST). However, the extent to which the high latitudes …

The tectonics, geography and climate of the Cretaceous world were very different from the
modern world. At the start of the Cretaceous, the supercontinent of Pangaea had just begun …
