Fusulinids
The fusulinids as a large,warm-water foraminifera were quite sensitive to water temperature. The optimalwater temperature for recent warm-water benthic foraminifera with livingsymbionts, and consequently for fusulinids, is 20–30°C, while the lower limit is 14–16°C. Three climatically-determinedassemblages were distinguished in Zagros and ...The fusulinids as a large, warm-water foraminifera were quite sensitive to water temperature.

Fusulinids are the earliest lineage of foraminifera thought to have evolved symbiosis with photosynthetic organisms. Fossils of fusulinids have been found on all continents except Antarctica; they reached their greatest diversity during the Visean epoch of the Carboniferous. In the Conglomerate Mesa area in the southeastern Inyo Mountains, east-central California, a series of distinctive fusulinid assemblages ranging in age from late Artinskian to Kungurian or Roadian was developed in units 7-10 of the sedimentary rocks of Santa Rosa Flat (part of the Owens Valley Group). The fauna of unit 7 shows some eastern Klamath Mountains affinity, but most of the species in ...More highly developed fusulinids with which Millerella is commonly associated in post-Morrowan Pennsylvanian rocks distinguish these strata from the Zone of Millerella. Rocks referred to the Zone of Millerella are widespread in the midcontinent region; ...Fusulinids are an important group offossil forams, which ranged in time from the Ordovician to the Permian. Fusulinids are the only foram group to have possessed a microgranular calcareous test, which is characteristically shaped like a fat cigar or grain of rice. Some fusulinids (like these) could attain large sizes.

Fusulinids are best adapted to warm shallow-marine conditions, although a few genera are able to endure warm-temperate water. One remarkable feature of the studied fusulinids is that their generic diversity, especially during the Sakmarian, was much lower than that of coeval fusulinids from tropical warm-water regions. Also, the dominant genera ...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 from the former have evidently higher diversities than those from the latter in general, especially during Kungurian and the succeeding middle Permian. Specifically, in the Asselian to Artinskian (early Permian) times, the blocks of Group 2, except the Tengchong Block, hosted fewer fusulinid genera than those of Group 1. ….
