 ==== Dinoflagellates and Acritarchs ====
+Dinoflagellates (and Acritarchs) are an important constituent of palynological preparations. They indicate marine conditions and are biostratigraphically important. As organic-walled palynomorphs they can also be found in coarser-grained (i.e., higher energy) sediments than other microfossil groups.

   * complex classification on the “tree-of-life”, indeed it has been problematic in the past to classify dinoflagellates as plants or animals. Some are photosynthetic (“autotrophic”), some are not (“heterotrophic”) and some are motile. Sexual reproduction is rare. However, current viewpoints (e.g. Armstrong and Brasier, 2005) favour inclusion within the realm of zoology rather than botany
