Fossil foraminifera. Coloured scanning electron micrograph (SEM) of the fossil shell of the single-celled protozoan Textularia sp. belonging to the order Foraminifera. Foraminifera shells are composed of several chambers & usually penetrated by pores through which the cellular contents are extruded. The organisms live in the sea or salt- water lakes. Foraminiferan shells form an important component of chalk and of many deep sea oozes. In previous geological ages Foraminifera occurred in such enormous numbers that their shells, largely of calcium carbonate, have formed immense fossil deposits seen today as limestone.
