What are fusulinids in geology? Fusulinids. Fusulinids were small marine organisms that were common inhabitants of the world’s seas during the Pennsylvanian and Permian periods, from about 323 to 252 million years ago. The earliest fusulinids occur in rocks deposited during the late Mississippian Period, more than 323 million years ago.

Foraminifera with hard tests are scarce until the Devonian, during which period the fusulinids began to flourish culminating in the complex fusulinid tests of the late Carboniferous and Permian times; the fusulinids died out at the end of the Palaeozoic.Particularly abundant in some limestones are fusulinids - fossils shaped like wheat grains. These one-celled animals floated in the warm tropical water. When they died, their skeletons were preserved in the lime mud of the ocean floor. Fusulinids can be seen in many of the limestone blocks used for building on the preserve.Fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures. Igneous rocks form at temperatures and pressures that are high enough to destroy any organic remains.Permian rock layers contain several of the fossil record’s greatest evolutionary enigmas.

Most of the rocks that comprise the San Juan Islands are considered parts of accreted terranes. The rocks and their fossils speak of exotic origins, bits and pieces of the ocean floor and island arcs that came from far away.Figure 6: Other common fossils seen in thin section and in the field using information from Sorauf (1978), Fontaine et al.
