1000 CE से पहले शुरू में वहां मिसिसिपियन संस्कृति का उत्थान हुआ जिसके लोगों ने वर्तमानकालीन सेंट लुई और वर्तमानकालीन कॉलिंसविल, इलिनॉयस के निकट काहोकिया में मिसिसिपी नदी के आसपास क्षेत्रीय राजनीतिक केंद्र स्थापित किए।

मिसिसिपियन संस्कृति ने इन टीलों को पूरे मध्य मिसिसिपी और ओहियो नदी की घाटियों में छोड़ दिया था जो दक्षिण-पूर्व के साथ-साथ ऊपरी नदी तक फैला हुआ था।

mississippian's Usage Examples:

Mississippian SystemThe Mississippian system was formerly regarded as a part of the Carboniferous, and was described under the name of Lower Carboniferous, or Subcarboniferous, without the rank of a system.

United States, in Missouri, Pennsylvania, West Virginia, Kentucky, Ohio and elsewhere, there is an unconformable junction between the Lower and Upper Carboniferous, representing an interval of time during which the lower member was strongly eroded; it has even been proposed to regard the Mississippian (Lower Carboniferous) as a distinct geological period, mainly on account of this break in the succession.

(See Bernician, Tuedian and Avonian.) At an early period, owing to the immense commercial importance of the coal seams, it became the practice to distinguish a " productive " (flotzfiihrend, terrain houiller) and an "unproductive," barren (flotzleerer) Lower Carboniferous; these two groups correspond in North America to the " Carboniferous " and " Sub-Carboniferous " respectively, or, as they are now sometimes styled, the " Pennsylvanian " and " Mississippian."

Superficially, each is a simple rolling plateau, much broken by erosion (though considerable undissected areas drained by underground channels remain), especially in the east, and dotted with hills; some of these are residual outliers of the eroded Mississippian limestones to the west, and others are the summits of an archaean topography above which sedimentary formations that now constitute the valley-floor about them were deposited and then eroded.

This older classification, which has little support except that which is traditional, is still adhered to by many geologists; hut the fact seems to be that the system is set off from the Pennsylvanian (Upper Carboniferous) more sharply than the Cambrian is from the Ordoviciao, the Silurian from the Devonian, or the Devonian from the Mississippian.

The explanation of the apparent conformity of the strata from the Cambrian to the Pennsylvanian in some parts of the west, with no fossils defining with certainty any horizon between the Ordovician and the Mississippian, is one of the open problems in the geology of the United States.

Pennsylvanian SystemThe Pennsylvanian or Upper Carboniferous system overlics the Mississippian unconformably over a large part of the United States.

When deposition was renewed in the interior of the continent, the formations laid down were largely non-marine, and, over great areas, they rest upon the Mississippian unconformably.

Subcarboniferous, or Mississippian.

Mississippian.
