Fusulinid fossil
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).INTRODUCTION. 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.

Some fusulinids (like these) could attain large sizes. Fusulinids are used as zone fossils in biostratigraphy to subdivide the Carboniferous and Permian periods. Specimen A4b is a “fusulinid limestone”. This is a limestone rock containing abundant and large fusulinid forams, visible with the naked eye. In some cases the internalThey were marine protists (single-celled eucaryotes) that lived from the late Early Carboniferous to the end of the Permian Period. Fusulinids are foraminiferans of …Jan 1, 2001 · Conodonts are closely similar to species in the Ural Mountains region of Russia and Kazakhstan, as well as the American midcontinent. The co-occurrence of fusulinids and conodonts in the Keeler basin results in a better correlation of zones based on these two groups of fossils than generally is possible.
fusulinids (e.g., Thompson, 1954) and other fossil assemblages from the Admire Group and overlying lower part of the Council Grove Group, and correlative units throughout North America, were dated as earliest Permian (early Wolfcampian). Ross (1963, fig. 11), in a study of the fusulinids of the WolfcampianThe earliest fossil record of foraminifera is from the Cambrian Period (about 550 million years ago). It diversified slowly in the early Paleozoic but had a rapid growth in Carboniferous and Permian times when large-sized fusulinid foraminifera evolved.

Fusulinid data used to produce the fusulinid density maps comes Index fossils used for the Pennsylvanian fossils occur in the lava, and blebs of lava appear to be contained within the limestone. Thus it would be seen that the lava was extruded onto the sea bed during the deposition of limestone (Gobbett, 1973).

Because conodont fossils are distributed all over the world, they are utilized internationally to date Mississippian rocks.
