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.
