Short summary
Species of two important diatoms (algae with silica skeletons and important primary producers) are described formally and incorporated into existing biozonation schemes allowing correlation of Paleocene to Miocene strata in the North Sea, important for hydrocarbon exploration as well as for environmental interpretation. Their abundances are linked to environmentally stressed conditions, including increased global warming and periods of nutrient influx from rapidly eroding land masses nearby.
