Introduction
During the Paleozoic Era (541 to 251.9 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era.
Paleozoic Resources
The Paleozoic Era is further divided in to seven periods/sub-periods: the Cambrian, the Ordovician, the Sulurian, the Devonian, the Mississippian, the Pennsylvanian, the Permian. A few examples of NPS resources in each time Period are highlighted below, from youngest to oldest.
