Fusulinid

New foraminiferal assemblages consisting of fusulinids and smaller foraminifers have been described from a basalt/carbonate rock block (locality 51F7) and small outcrop of thin-bedded limestone (locality 51F6) located near the entrance to Marble Canyon west–southwest of the town of Cache Creek in southern British Columbia, Canada. The locality 51F7 contains diverse fusulinid and smaller ...

The highest peak in fusulinid diversity within the Pennsylvanian-Cisuralian interval and a major marine transgression documented in many regions in Northern Pangaea took place during the latest Gzhelian to earliest Asselian and evidence for this is now extended to southern Pangaea.

Materials and techniques.Here, the Owens Valley is composed of several sedimentary lithologies, including silty fusulinid-bearing limestone, lenticular organic limestone (within which brachiopods, corals, crinoids and bryozoans can be found), calcareous shales, sandy limestone, limestone-mud breccias, and relatively pure limestones.ABSTRACT: Analysis of fusulinids from the Bug Scuffle Limestone Member of the Gobbler Formation along the western escarpment of the Sacramento Mountains in south-central New Mexico demonstrates that all four Desmoinesian regional fusulinid zones documented in Midcontinent and Southwest North America are present in the stratigraphic unit.Materials. The Pseudoschwagerininae appeared abruptly in the early Permian fusulinid radiation. Among the four genera mainly developed in this radiation, Pseudoschwagerina, Robustoschwagerina, Sphaeroschwagerina, and Zellia, Pseudoschwagerina exhibits inflated fusiform to subspherical adult test forms (), while the other three exhibit subspherical to spherical test forms (Fig. 1C,H,I).

lower fusulinid assemblage studied in this report seems to have come from the "black band of bitu­ minous fusuline limestone" about 8 meters thick near the middle of the Wordiekammen Limestone that Forbes, Harland, and Hughes (1958) called the "Mid Wordiekammen Limestones." Forbes (1960) placed the Carboniferous-Permian boundary withinJul 8, 2012 · The shell of a fusulinid is very complex. It is made of a granular calcite wrapped along the axis of the football in a series of chambers with internal walls. Each coil wrapped completely over the earlier coils, making the shells involute. They are most commonly studied in section to reveal the internal complexity. Wilde GL (1990) Practical fusulinid zonation of the Permian basin. W Texas Geol Soc Bull 29: 5–15, 28–34.
