This paper highlights the potential of combining (organic) geochemical proxies with dinoﬂagellate cyst studies. Firstly, such a multiproxy approach is a powerful tool for palaeoceanography and for providing insights into the natural variability of the climate system in the past. Geochemical proxies have the advantage of providing absolute estimates for environmental variables, but the importance of assemblage studies is especially highlighted here because fossil assemblages are excellent indicators of large-scale changes in surface water masses such as shifts of ocean currents. Secondly, the geochemical proxies can also be exploited to determine the environmental preferences of individual species. Until now, only the temperature preference of extant and extinct dinoﬂagellate cyst species in fossil assemblages has been investigated by comparing them directly to geochemical proxy. Finally, an integrated geochemical and palynological approach is useful for biostratigraphy because it can improve the existing biozonations, provide chronostratigraphic calibration and/or aid in identifying stage boundaries.

Biological and Geological Perspectives of Dinoflagellates
This volume provides an overview of current research on fossil and modern dinoflagellates, as well as highlighting research areas for future collaboration, following the DINO9 International Conference in Liverpool. The volume is organized into four themes, with a review paper for each theme written by the key-note speaker. Each theme also includes a future research foci note following discussion during the conference. The contributions are organized into the following sections: environmental change, ecology/palaeoecology, life cycles and diversity, and stratigraphy and evolution. Also included are notes from two workshops: culture experiments and dinocysts as palaeoceanographic tracers. This volume will be of interest to both the biological and Micropalaeontological communities.
