Abstract

Diatoms are found in a wide variety of habitats. Fossil evidence suggests that diatoms are of relatively recent geologic origin in comparison to other algal groups. The oldest known fossil specimens come from the Jurassic Period (Vinyard 1979). Centric diatoms are predominant in the more ancient strata and also are the predominant forms in present day oceans (Vinyard 1979). Fossil diatoms are used to locate oil strata and water strata, to record the movement of glaciers and to reconstruct paleoecological environments.
