W 2. Which era is the Mississipian period part of? Cenozoic Paleozoic Mesazoic Proterozoic

The Mississippian period is part of the Paleozoic era, which spanned from about 541 to 250 million years ago. This period is particularly known for the development of extensive shallow marine environments and the flourishing of coral reefs, providing a home for a diverse array of aquatic life, including fish and early amphibians. During the Mississippian, large limestone deposits formed, largely because of the accumulation of marine organisms’ shells and skeletons. This era set the stage for the evolution of terrestrial plants and animals, ultimately leading to significant ecological developments in the following periods.
