Fossils of fusulinids have been found on all continents …In some porcelaneous species, small depressions in the surface ornamentation give the appearance of pores. Another type of wall structure, called microgranular, is made of tightly packed equidimensional rounded grains of calcite. This wall type is found in many Paleozoic foraminifera including the fusulinids. Figures 1-6.Fusulinids—Fusulinids (fig. 12) were small marine organisms that populated the seas worldwide during the Pennsylvanian Subperiod and Permian Period.
