Foraminifera are single-celled organisms (amoeboid protists) with calcareous shells that produce a network of reticulating strands of cytoplasm to catch food and live predominantly in seawaters. Larger benthic foraminifera are a group of foraminifera with relatively large size (around 1-5 cm, rarely up to 20 cm).2) The fusulinid assemblages give substantial information concerning the paleogeography and paleoenvironment.
