Consequently, one apparent controlling factor of the large-scale distribution of fusulinids (e.g. diversity gradient), would be the sea surface temperature ... 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 are often used as index fossils because they were present during the Paleozoic Era and are useful for determining the ages of marine rocks.

The Fusulinidae is a family of fusulinacean foraminifera from the upper Carboniferous (Lower Pennsylvanian, Morrowan) to the Upper Permian ( Guadalupian ), tests of which are fusiform to subcylindrical with walls of two to four layers. Are planispirally coiled throughout or with early whorls at a distinct angle to the later plane of coiling. Some fossils, not clearly related to those below, are probably migrants from other regions. Among the distinctive features of the fauna are fusulinids and ammonoids of larger size and more complex internal structure than those of the Pennsylvanian (such as Parafusulina, Polydiexodina, Perrinites, and Medlicottia).Fusulinids—Fusulinids (fig. 12) were small marine organisms that populated the seas worldwide during the Pennsylvanian Subperiod and Permian Period.

Terrestrial leaf and insect fossils have Foraminifera are amoeba-like, single-celled protists (very simple micro-organisms). They have been called ‘armoured amoebae’ because they secrete a tiny shell (or ‘test’) usually between about a half and one millimetre long. They get their name from the foramen, an opening or tube that interconnects all the chambers of the test. Permian marine animal fossils include mollusks, brachiopod...
