Foraminifera | Single-celled organisms are perhaps the simplest form of animal life and are found throughout the world in all types of environments, but most do not lend themselves to fossilization. The foraminifera are a group of single celled organisms that secrete a calcareous test around the soft body. The hard test often fossilizes and, in some instances, they are so numerous that they form entire rock beds. The foram test is usually a series of chambers organized in a wide variety of shapes and arrangements. Virtually all forams are microscopic, but some groups grow large enough that they can be seen without magnification. In the Pennsylvanian one such group is the fusulinids which form football shaped tests that can be over 5 mm long. In the Finis, fusulinids are abundantly represented by the genus Triticites and in certain strata they are so abundant that they can be scooped up by the handful. ---------------------------------------------------------------------------------------------------------------------------------------- Scroll through images or click to enlarge.
