Mammals rose to prominence in terrestrial ecosystems after the Cretaceous–Paleogene mass extinction, but the mammalian lineages characteristic of Paleogene faunas began their …
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 …
Reconstructing long-term continental temperature change provides the required counterpart to age equivalent marine records and can reveal how terrestrial and marine temperatures …
Early Eocene global climate was warmer than much of the Cenozoic and was punctuated by a series of transient warming events or 'hyperthermals' associated with carbon isotope …
Andean uplift played a fundamental role in shaping South American climate and species distribution, but the relationship between the rise of the Andes, plant composition, and local …
We describe the sedimentology, geochronology, and geochemistry of the Early Cretaceus Sao Khua Formation of the Khorat Basin, northeastern Thailand, and report a temporal …
Greenhouse climates such as the Late Cretaceous period provide important reference frames for understanding modern anthropogenic climate change. Upper Cretaceous …
Earth's climate sensitivity, defined as the temperature increase for a doubling of partial pressure of carbon dioxide (p CO 2), and the mechanisms responsible for amplification of …
Early Eocene climates were globally warm, with ice-free conditions at both poles. Early Eocene polar landmasses supported extensive forest ecosystems of a primarily temperate …
