		Microfossils are a common feature of the geological record, from the Precambrian to the Quaternary, and are found in most marine and terrestrial sediments.
		While every Kingdom of life is represented in the microfossil record, the most abundant forms are protist skeletons or cysts from the phyla Chrysophyta, Pyrrhophyta, Sarcodina, acritarchs and chitinozoans together with pollen and spores from vascular plants.
		Micropaleontology is traditionally divided into three areas of study on the basis of microfossil composition, which can be calcereous, siliceous, or organic.

		The Pyrrhophyta, Chrysophyta, Cryptophyta, Charophyta, Bacillariophyta, Xanthophyta and Euglenophyta are mainly unicellular algae.
		Dinoflagellata (Pyrrhophyta) are also called fire algae for their ability to bioluminesce or glow.
		They are also commonly called dinoflagellates due to the presence of flagella, which provide a whirling motion (dinein= to whirl).

		Toxinogenic algae are found in the divisions Chrysophyta, Pyrrhophyta, and Cyanophyta.
		They also produce other organic compounds that may react with chemical disinfectants to produce toxins that may be ingested with drinking water.
		The majority of the known seafood toxin syndromes are associated with bivalves that can accumulate a variety of toxins produced by dinoflagellates (Pyrrhophyta) and diatoms (Chrysophyta).

	Ethnobotanical Leaflets
		Algae are a "group of plants" that dominate the aquatic environment (Raymount, 1984).
		Organisms that make up the algae include representatives from three kingdoms and seven divisions: cyanochloranta and prochorophyta (from Kingdom Monera), pyrrhophyta, chrysophyta, phaeophyta, and rhodophyta (from Kingdom Protista), and chlorophyta (from Kingdom Plantae).
		All seven divisions are called algae because of a lack of roots, stems, and leaves; and most algal cells are fertile.

	Life History and Ecology of the Dinoflagellata
		Some species will parasitize other organisms, such as zooplankton and other protists, filamentous algae, or fish.
		The Dinoflagellata are sometimes called Pyrrhophyta, meaning "fire plants".
		This is because some species are capable of bioluminescence, in which chemicals made by the organism produce light in a chemical reaction.

	Chapter 27 Remarks
		Euglenophyta and Pyrrhophyta are fairly primitive algae, but have wonderfully interesting features.
		The dinoflagellates (Pyrrhophyta) are responsible for red tides and make many shellfish toxic to humans and kill fish when dinoflagellates are abundant.
		A common Bermuda observation in the Tropical Biology course is these critters "flashing" in the bowl during nocturnal urination (the toilets use sea water to conserve limited fresh water).

		Dinoflagellates can be classified both botanically and zoologically; however, they are typically put in the botanical division Pyrrhophyta.
		Within the Pyrrhophyta are both unarmored and armored forms of the dominant, motile flagellated stage.
		Unarmored dinoflagellates do not have thecal or wall plates arranged in specific series, whereas armored species have plates that vary in thickness but are specific in number and arrangement.

	Classification and Identification of Pfiesteria and Pfiesteria-Like Species
		This article is part of the National Conference on "Pfiesteria: From Biology to Public Health" and covers what is currently known about the higher-level placement of the Pfiesteria-like organisms and the taxonomic relationship between P.
		Pfiesteria and several Pfiesteria-like genera are dinoflagellates classified in the botanical division Pyrrhophyta.
		In that work (11) and elsewhere, plate tabulation is considered the most important morphological characteristic to differentiate within the division Pyrrhophyta at the family or subfamily rank.

	Dinoflagellates
		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.

		Alga (-ae) - a term for a very diverse taxonomic group all containing chlorophyll a but lacking vascular tissues found in higher plants; may be unicellular or multicellular organisms, found in marine, freshwater, living endophytically in other plants and algae, soil environments, some can even by airborne.
		This course focuses on freshwater algae found in the following phyla: Cyanophyta (blue-greens), Chlorophyta (greens), Euglenophyta (flagellated greens), Pyrrhophyta (dinoflagellates), Chrysophyta (browns, yellow-greens, diatoms) and the Rhodophyta (reds).
