Fusilinids
The Permian Period was a critical time interval during which various blocks of the Qinghai-Tibetan Plateau have experienced profound and complex paleogeographical changes. The supercontinent Pangea was formed to its maximum during this interval, hampering a global east-to-west trending equatorial warm ocean current. Meanwhile, a …Fusulinids from the Howe Limestone Member (upper part of the Red Eagle Limestone, lower part of the Council Grove Group) are described here for the first time. The Howe fauna is particularly significant because it represents the earliest fusulinids known to occur above the new conodont-based Carboniferous (Pennsylvanian)-Permian boundary at the Glenrock Limestone Member-Bennett Shale Member ...

Knapping:FUSULINIDS were reported from the metasedi-mentary "Garlock Series" of the El Paso Mountains in Kern County, California by Dib-blee (1952, p. 15-19) who quoted C. W. Mer-riam's identification of Schwagerina sp. and age assignment of Early or Middle Permian. How-ever, this interesting fauna has not been de-scribed or illustrated.About this image. Axial section of an Upper Paleozoic fusulinid from the Sandia Mountains near Albuquerque, NM. Fusilinids are marine microfossils of extinct single cell organisms that lived from Mississippian to Permian time. Because they had a world-wide distribution, and evolved rapidly, they can be used to correlate sedimentary rocks of ...Abstract.

Other fossils found in the radiolarian chert of this terrane are derived from Asian seas, containing Asiatic fusilinids, corals, sponges, brachiopods, bryozoans, and conodonts. Therefore, this terrane is interpreted as a remnant of the Panthalasa Sea (Cordey et al., 1992; Cordey and Schiarizza, 1993; Cordey, 1996; Orchard et al., 2001; Johnston ...especially for fusulinids, which have been studied rarely, due to their traditional use primarily for biostratigraphy.

Fusulinids are widely distributed in Middle Carboniferous to Lower Permian shallow marine deposits of Spitsbergen, the main island of Svalbard Archipelago ( Figure 1 ). Upper Paleozoic strata exist throughout the archipelago, but the largest outcrops occur in the central Spitsbergen region.
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 ...The 2 core samples used in the experiment were taken about 30.5 cm (1 foot) apart, 1 from a stylolitic zone and the other sample from an interval having fusilinids and pseudo-oolites. There was an artesian brine zone noted at about 183 m (600 feet) on the drillers log (Condra and Reed, 1939). The sample of the white, finely crystalline ...Hi everyone.

Permian fusilinids, Cache Creek Terrane, Marble Canyon, B.C..Fusulinids are suspected to have hosted photosymbionts as modern larger benthic foraminifera (Ross, 1972, Shi, 2008, Groves et al., 2012), and their shells may have been used functionally as the greenhouses with the keriotheca honeycomb in the interior wall serving as "pore cups" to hold these symbionts (Shi, 2008). Accordingly, the large ...
They indicated that the conodonts, fusilinids, and ammonoids at that location are Early Permian (Asselian). On the basis of a collection of more than 40,000 ammonoids, Emilites is numerically a relatively unimportant component of Upper Pennsylvanian ammonoid assemblages. However, Ru zhencev and Bogoslovskaya (1971) suggested that the co-ocThey are possibly a large part of the volume of organic material that created middle eastern oil.
