Description: Information on these organisms including their fossil record, classification, biology and life cycle with a number of images of individual species.
Dinoflagellates are protists which have been classified using both the International Code of Botanical Nomenclature (ICBN) and the International Code of Zoological Nomenclature (ICZN), approximately half living dinoflagellate species are autotrophs possessing chloroplasts and half are non-photosynthesising heterotrophs. It is now widely accepted that the ICBN should be used for their classification. Dinoflagellates and their cysts belong to the Division Pyrrhophyta (literally "fire plants"), Class Dinophycaea, the related Class Ebriophyceae (also in the Division Pyrrhophyta) includes the ebridians which have internal siliceous skeletons, are extant and have a fossil record beginning in the Palaeocene. An important point to remember about dinoflagellates is that the vast majority of the fossil record consists of cysts (dinocysts), and only 10% of living dinoflagellates are known to produce cysts.
