The extinction of the dinosaurs and around three-quarters of all living species was almost
certainly caused by a large asteroid impact 66 million years ago. Seismic data acquired …

Abstract Short-lived (10 4–10 5 years) carbon isotope excursions (CIEs), many of which are
associated with some degree of ocean warming, are a feature of the warm climates of the …

The fossil record of marine microplankton provides insights into the evolutionary drivers
which led to the origin of modern deep-water plankton, one of the largest components of …

Coccolithophores are major producers of ocean biogenic calcite, but this process is
predicted to be negatively affected by future ocean acidification scenarios. Since …

Coccolithophores are typically thought of as photoautotrophs, yet a few genera inhabit sub-
euphotic environments with insufficient light for photosynthesis, suggesting that other carbon …

After the Chicxulub impact and mass extinction at the Cretaceous-Paleogene boundary (K-
PgB), ecosystems haltingly recovered under unstable conditions. An early Danian (65.9 Ma) …

The traditional separation between primary producers (autotrophs) and consumers
(heterotrophs) at the base of the marine food web is being increasingly replaced by the …

The Paleogene was punctuated by perturbations of the global carbon cycle, many
associated with transient global warming events (hyperthermals). The Dan-C2 event (~ 160 …

The evolutionary and ecological story of coccolithophores poses questions about their
heterotrophy, surviving darkness after the end‐Cretaceous asteroid impact as well as …

The global heterogeneity in export productivity after the Cretaceous‐Paleogene (K‐Pg)
mass extinction is well documented, with some sites showing no change on geologic …
