Abstract
The palaeoecological significance of calcareous dinoflagellate cysts is illustrated by various examples. Genetically fixed and ecologically triggered character traits are distinguished. A summary is given regarding intraspe-cific variability, cyst size and shape, wall thickness, size and shape of the calcitic wall crystals, paratabulation, and archeopyle morphology based on the knowledge, which has been accumulated during the last two decades. Diversity and characteristic cyst associations from different localities are compared. Information on sea level changes, water temperature, oceanographic distribution, and nutrient conditions can be gained from the investigated character traits of calcareous dinoflagellates.
