Mississippian Period

The Mississippian Period, approximately 358 to 323 million years ago, was a time in Earth's history marked by extensive shallow seas covering large parts of what is now North America. During this period, diverse marine life thrived, including early fish, corals, and shellfish. The seas fostered the development of thick limestone deposits, which are still found today. It also saw the appearance of the first significant fertile river valleys, setting the stage for later terrestrial ecosystems. Overall, the Mississippian was a dynamic era characterized by vibrant marine ecosystems and important geological formations.
