Paleozoic Geology

The Paleozoic era was made up of a period of time that started 600 million years ago and finished around 200 million years ago. At the start of the first marine life, brachiopods and trilobites, showed up. The ending of the Paleozoic Era more or less corresponds to the time of the appearance of the dinosaurs.

The Paleozoic Era was broken up into six periods, these are: The Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. The Carboniferous period was divided into two periods, which consisted of the Mississippian, which was the most ancient, and the Pennsylvanian the latest.

Throughout the Paleozoic Era there was a good amount of geological activity going on. North America was exhausted of a lot of the seas that covered it. Once the mountains and hills were formed, the land was one more time submerged and at times a great deal of the world was under water. During this era a lot of the world’s oldest coal deposits and fossil fuels formed.
