A compilation of foraminiferal stable isotope measurements from southern high latitude
(SHL) deep-sea sites provides a novel perspective important for understanding Earth's …

Most contemporary angiosperms (flowering plants) are insect pollinated, but pollination by
wind, water or vertebrates occurs in many lineages. Though evidence suggests insect …

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

Archaeal membrane lipids are widely used for paleotemperature reconstructions, yet these
molecular fossils also bear rich information about ecology and evolution of marine ammonia …

Biodiversity is not evenly distributed among related groups, raising questions about the
factors contributing to such disparities. The sunflower family (Asteraceae,> 26,000 species) …

The question why non-avian dinosaurs went extinct 66 million years ago (Ma) remains
unresolved because of the coarseness of the fossil record. A sudden extinction caused by …

There is an abundance of evidence for short intervals of cold climatic conditions during the
Early Cretaceous. However, the lack of a high-resolution, long-term Early Cretaceous …
