Fusulinids—Fusulinids (fig. 12) were small marine organisms that populated the seas worldwide during the Pennsylvanian Subperiod and Permian Period. The earliest fusulinids occur in rocks deposited during the late Mississippian Subperiod. Fusulinids became extinct during the mass extinction at the end of the Permian Period. Pires De Lima et al.

It diversified slowly in the early Paleozoic but had a rapid growth in Carboniferous and Permian times when large-sized fusulinid foraminifera evolved.Cross section of a fossilized fusulinid. Courtesy of Kansas Geological Survey. Lithify and Fossilize. The shallow warm seas supported enormous populations of invertebrates, fish, amphibians and plants. These creatures took calcium carbonate (CaCO3) out of the water and secreted it, forming shells or skeletons.Guide to Fossil Classification. Table 0.1 summarizes the kingdoms in the Linnaean classification system that we will follow for this course. Most of the groups we will be examining are part of Kingdom Animalia, but there are a few exceptions.
