Fusulinids fossils
Fusulinid, any of a large group of extinct foraminiferans (single-celled organisms related to the modern amoebas but having complex shells that are easily preserved as fossils). The fusulinids first appeared late in the Early Carboniferous Epoch, which ended 318 million years ago, and persistedSep 6, 2023 · Fusulinids were omnivorous, eating via reticulopodia (cell extensions), which projected through pores in the test to catch small creatures. The shell is secreted by the protoplasm of the cell. Fusulinids went extinct with the Permian-Triassic extinction event, making it a good index fossil. Other fossil colonial corals include Stelechophyllum and Siphonodendron. Because conodont fossils are distributed all over the world, they are utilized internationally to date Mississippian rocks. Index fossils used for the Pennsylvanian Period are fusulinid foraminifers and the pollen and spores from the coal forests prevalent during that time.
