Fusulinid.
The fusulinid faunas are composed largely of taxa of the North American craton, especially the south-central USA, with important endemic constituents and some McCloud Limestone forms, representing the Eastern Klamath terrane. Conodonts are closely similar to species in the Ural Mountains region of Russia and Kazakhstan, as well as the American ...
The fusulinid system accepted is that presented in "The reference-book on the Paleozoic Foraminifera sys-tematics" (Rauzer-Chernousova et al. 1996). CalculationsThe fusulinid fossils in terranes of the Northwest are called Tethyan fusulinids because they are types that existed in the large sea known as the Tethys Sea on the east side of the supercontinent Pangaea. The Tethyan fusulinid fossils suggest that the terranes came most of the way across the Pacific Ocean basin, from tropical latitudes, and ...stratigraphic focus of fusulinid research has led fusulinid workers to overlook taphonomic features. Finally, most fu-sulinids are studied as thin sections of limestone in which epibionts are not readily visible. The tests of 63 percent of the fusulinids examined had a least one encrusting epibiont (Fig. 5A). The only encrust-Our results show that fusulinid global provincialism was high in the Asselian, Sakmarian, and Artinskian, driven by the development of multiple fusulinid bioregions in and near the Tethys Ocean. During the Asselian, Uralian sites and nearby regions of western Tethys were distinct from eastern Tethys, while stations in Arctic Russia and Norway ...Fusilinid limestone contains solid fusulinid shells. Fusilinids are single-celled animals with shells that secrete microgranular calcite. Reef-like limestone is created with aquatic fauna and flora fossils. This type of limestone includes bivalves, gastropods, trilobites, brachiopods, and coral.
In the Shanmutang section, fusulinid samples were collected from beds 12 and 13. Although a few could be recognized as Parafusulina and Chusenella, most specimens from bed 12 are poorly preserved and difficult to be identified precisely. In bed 13, fusulinid fossils are better preserved and more diversified.

The Fusulinida is an extinct order within the Foraminifera in which the tests (shells) are composed of tightly packed, secreted microgranular calcite. Like all Forams, they are single-celled organisms. In advanced forms the test wall is differentiated into two or more layers.
