Short summary
This contribution integrates new data on the main components of organic matter, geochemistry, and stable isotopes for the Cenomanian to Coniacian stages of the Late Cretaceous, along a north–south transect from the Cretaceous Western Interior Seaway to the equatorial western Atlantic and Southern Ocean. Distinct palynological assemblages and geochemical signatures allow insights into palaeoenvironmental conditions and water-mass evolution during this greenhouse climate period.
