Fusulinid Limestones--One group of the single-celled animals called Foraminifera is known as the fusulinids. These small animals, whose shells look like grains of wheat, were abundant during the Pennsylvanian and Permian periods, and many of the rocks of those ages are almost solid masses of fusulinid shells. Both limestones and shales contain ...

Crinoid fossils are most commonly found as "columnals," pieces of the stalk that hold the head (calyx) above the surface. The calyx and the holdfast are only occasionally preserved as fossils. Crinoids are still around today; those in shallow water are mostly stalkless, while those with stalks are restricted to deep water.

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. sian fusulinids contain little in terms of the small forms and none contains the diversity of the Ohio faunas.

Norton (1975) did not find any small fusulinids in his study of the Brush Creek ...The fusulinids as a large, warm-water foraminifera were quite sensitive to water temperature. The optimal water temperature for recent warm-water benthic foraminifera with living symbionts, and consequently for fusulinids, is 20–30°C, while the lower limit is 14–16°C.The Fusulinida (commonly denominated fusulines, fusulinids, fusulinoids or fusulinaceans) are a group composed of six superfamilies: Ozawainelloidea, Staffelloidea, Schubertelloidea, Fusulinoidea, Schwagerinoidea, and Neoschwagerinoidea (= Verbeekinoidea).
