Calcareous algae, fusulinids, and echinoderms disappeared at the top of Bed 8. None of the species were found in the P–Tr transition beds or the overlying Feixianguan Formation, as shown in Fig ...The described fusulinids of the Moscovian Stage are found in the Asad-Abad section of the Sanandaj-Sirjan tectonic zone of Iran. Five successive fusulinid assemblages are distinguished. Three lower of them belong to the Kashirian Substage, the other two to the Podolskian Substage. The section studied is correlated with most complete sections of the Moscovian Stage in the western Tethys. Two ...Permian fusulinids of the Bawei Section from southern Baoshan Block in western Yunnan, China, adds more data concerning biostratigraphy and paleogeography of this block. These fusulinids comprise 31 species of 11 genera and could be, ascendingly, grouped into two assemblages: Yangchienia-Nankinella assemblage and Chusenella-Rugosofusulina ...

Early Permian fusulinids from both northern and southern parts of the Baoshan Block (western Yunnan, Southwest China) are illustrated and compared with coeval fusulinid faunas from other northern peri-Gondwana areas to disclose paleogeographic information.

A closer look at the rock reveals many fossils. Most of these marine fossils are invertebrates (animals without backbones) such as corals, clams, snails, bryozoans (colonies of animals resembling sea fans), sea urchins, crinoids (a stalked animal distantly related to starfish and sea urchins), and ...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 fusulinid fossils in terranes of the Northwest are called Tethyan fusulinids because they are types of fusulinids that existed in

Fusulinids, one-celled animals that made shells, had proliferated in the Carboniferous and they continued to expand during the Permian. These critters were really large compared to most single-celled organisms, and some Permian types were more than a centimeter long. Their cross-sections reveal complex internal compartments where the animal ...Twenty-nine fusulinid species of 14 genera are determined in the Podolskian and Myachkovian substages (Pennsylvanian) of the southern Moscow Basin. All test sections are determined to genus level, except for the genera Schubertella and Fusiella. Since it is impossible to distinguish between these two genera in oblique test sections, they are identified to the family Schubertellidae. The ...
