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 internalMost fusulinid genera have high (or relatively good) biochronological value and are useful for making refined biostratigraphy and regional/inter-continental correlation. This family was derived from the Ozawainellidae in the early Bashkirian (Early Pennsylvanian) and flourished by the end of the Moscovian (Middle Pennsylvanian).A newly discovered Verbeekina assemblage from the Xiaoxinzhai Section in the Baoshan Block in western Yunnan, China, provides additional data for better understanding fusulinid biostratigraphy and the thermal condition of middle Permian (Guadalupian) seawater of this block.They were benthic creatures that moved upon the sea-bottom muds, eating other tiny organisms. Fusulinids are abundant in Nebraska's late Paleozoic rock record. They become extinct at the end of the Permian. This is a rock consisting of many fusulinids. Their shape is often compared to that of a grain of rice.The process results in finely laminated mounds and columns that have been found before in the fossil record. One particularly characteristic shape is a cone—precisely like the row of triangles ...To meet different research needs, multiple sections of fusulinid fossils, including axial, sagittal and tangential sections, could be produced, and axial sections are preferred for identification as they contain the most useful features (Sheng et al., 1988; Vachard et al., 2010). This slice-based identification of fusulinids is very beneficial ...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).
