Mississippian

1. of or relating to the state of Mississippi or the Mississippi River
2. (in North America) of, denoting, or formed in the lower of two subdivisions of the Carboniferous period (see also Pennsylvanian (sense 2)), which lasted for 30 million years
3. the. the Mississippian period or rock system equivalent to the lower Carboniferous of Europe

Mississippian

[¦mis·ə¦sip·ē·ən]
(geology)
The fifth period of the Paleozoic Era beginning about 350 million years ago and ending about 320 million years ago. The Mississippian System (referring to rocks) or Period (referring to the time during which these rocks were deposited) is employed in North America as the lower (or older) subdivision of the Carboniferous, as used in Europe and on other continents.
