Print Email. The Mississippian is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earliest/lowermost of two subperiods of the Carboniferous period lasting from roughly 358.9 Â± 0.4 to 323.2 Â± 0.4 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years.
The Silurian period (443-416 million years ago) was the shortest period of the Paleozoic Era. This is when the very first terrestrial plants and invertebrates (i.e., bugs) appeared, while the most important development in vertebrate life was the evolution of jawed fish.
