Variations in morphology and growth rate have also been observed in clonal communities of benthic foraminifera . Fossil Foraminifera appear in the Early Cambrian, at about the same time as the first skeletonized metazoans. For example, the Ant-arctic notodendrodids comprise several morphotypes, including spherical, tubular, and arborescent forms, some of them present together in a single species (27).

The unusual morphology of these foraminifera, “improbable” and rare, is mysterious clues to the natural survival of such organisms. The classification of foraminifera has been largely constructed on the basis of shell morphology, the nature of the wall, overall appearance, chamber arrangement, and specific morphological features, as pointed out in Loeblich and Tappan, 1988.

The oldest fossil foraminifera, from the Cambrian, are simple agglutinated tubes.Calcareous microgranular and porcellaneous tests evolved in the Carboniferous, and calcareous hyaline tests in the Permian.Over time, each of these groups has evolved many different forms, including large complex tests associated with reefs. They are among the most common and widespread groups of benthic foraminifera in the neritic zone (Murray, 1991). In this volume John Murray investigates the ecological processes that control the distribution, abundance, and species diversity of benthic foraminifera in environments ranging from marsh to the deepest ocean. foraminifera replace by sparry calcite (S). A Seminar on 1 April 7, 2017 2. %PDF-1.6 %���� Planktic foraminifera are single-celled eukaryotic organisms that live in the photic zone of the marine environment and exhibit passive floating lifestyles.
