Part A
The Late Paleozoic Era
The Mississippian, Pennsylvanian, and Permian Periods comprise the Late Paleozoic Era (see Figure 11-2). In Europe, the name Carboniferous is used to refer to rocks of Mississippian and Pennsylvanian age. The Permian Period is the youngest of the Paleozoic Era and was named for rocks in the Perm region of Russia. These rocks are exposed across North America, from the Appalachian Mountains to the Grand Canyon (see Figure 11-3).

Late Paleozoic Geologic Time
The Mississippian, Pennsylvanian, and Permian Periods stretch out over the last 100 million years or so of the Paleozoic Era. A simplified geologic time scale constructed from the 2020/03 ICS time scale is shown in Figure 11-3. It is not drawn to scale as its focus is including all of the Periods of the Phanerozoic Eon and all of the Epochs of the Cenozoic Era.
