The Middle Eocene Lutetian Samalut formation is among the best examples of anisotropic fossiliferous rocks in Egypt, where the effect of the anisotropic Nummulite Gizehensis fossils on the petrophysical behavior can be traced. The Samalut formation has been sampled and studied at Wadi Feiran in SW Sinai. Petrographically, it is composed …2) The fusulinid assemblages give substantial information concerning the paleogeography and paleoenvironment. Analysis of the Asselian and Sakmarian fusulinid assemblages indicates that the rocks in north Afghanistan were deposited in a tropical climate within a basin freely connected with basins in the Tien-Shan, the Pre-Caspian depression Kunlun.Fusulinid limestone from the Pennsylvanian of New Mexico, USA. (4.0 centimeters across at its widest) This small piece of fossiliferous limestone is dominated by fusulinids, an extinct group of unicellular, marine benthic organisms (Protista, Granuloreticulosa, Foraminifera, Fusulinina). They had relatively large, elongated, rice-like, microgranular, calcareous skeletons (tests).She discovered the Permian fusulinid assemblage described herein. This new microfauna is older than the first biozone of the Leonardian, but is different from all Latest Wolfcampian assemblages mentioned in the Americas, and contains several Tethyan taxa. This assemblage confirms that Guatemala received several migrations of Tethyan ...

Lamarck, 1801. Species. Numerous. A nummulite is a large lenticular fossil, characterised by its numerous coils, [1] subdivided by septa into chambers. They are the shells of the fossil and present-day marine protozoan Nummulites, a type of foraminiferan. Nummulites commonly vary in diameter from 1.3 cm (0.5 inches) to 5 cm (2 inches) [2] 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-

The major allochem of this facies is Fusulinid (60%) with 4 mm in size. This facies can be found in the form of medium - to - thick bedded limestones with inte rbedded gray shales ( Figure 3 (d) ).2) The fusulinid assemblages give substantial information concerning the paleogeography and paleoenvironment.

As an example, morphospecies identification on population level was conducted on Eopolydiexodina specimens from a single bed of the …The Cherry Canyon formation contains the youngest representatives of the fusulinid Parafusulina, the species in the lower part being the same as those in the underlying Brushy Canyon formation. It contains ammonoids at several horizons, but only the South Wells limestone member in the upper part contains diagnostic genera, such as Waagenoceras.

This transition was accomplished by the progressive development of internal epithecal deposits. By definition, the epitheca in Profusulinella is secreted only on the floors of chambers and septa. In Fusulinella, the epitheca is secreted ...

Six genera and 27 species of Permian fusulinids, of which four genera and 15 species are described as new, have been recovered for the first time from the Khan Formation in east-central Iran.Fusulinid biozones are acme or assemblage zones in which an abundant occurrence of the index and associated species is related to relative sea-level change and therefore the bases and tops of proposed zones are bound with unconformities, erosional surfaces or soil formations. Three fusulinid cycles are recognized in the "M" Formation of the ...

The fusulinid assemblages recovered in this study correlate well with the Russian Platform, Cantabrian Mountains, Central Iran, southern Urals, Donets Basin, and some other regions of the Tethyan ...Abstract. Agglutinated Foraminifera remained the dominant group in the Lower Palaeozoic but a spectacular increase in number and kinds of Foraminifera occurred in the Upper Palaeozoic with the rise of the calcareous microgranular group. With the advent of wholly secreted tests, Foraminifera became important contributors to limestones ...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.

The Permian (about 290-250 Ma) was a time of immense global change and unique paleogeographic configurations. Climate conditions evolved from a glacial icehouse Earth to a hothouse Earth. Land masses were assembled into one great continent of Pangea that extended from pole to pole and the mega-ocean Panthalassa dominated the Earth's surface.
