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 Carboniferous Period (in North America subdivided into the Mississippian and Pennsylvanian Periods) and the first half of the subsequent Permian Period (299 million to 251 million years ago) were the times of high oxygen, and the biota of the world at that time left clear evidence of the high oxygen.
