The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian.

In the USA the Carboniferous is usually broken into Mississippian ( earlier ) and Pennsylvanian ( later ) Periods.

The Mississippian is a subperiod in the geologic timescale or a subsystem of the geologic record.

The Mississippian is so named because rocks with this age are exposed in the Mississippi River valley.

In the official geologic timescale, the Mississippian is subdivided into three stages:

In the North American system, the Mississippian is subdivided into four stages:

There is no evidence for these being fed upon until the middle-late Mississippian,.

The entire area is actually a dissected plateau of Pennsylvanian and Mississippian age, but appears mountainous to the casual observer.

The late Mississippian culture is what the earliest Spanish explorers encountered, beginning on April 2, 1513, with Juan Ponce de León's Florida landing and the 1526 Lucas Vázquez de Ayllón expedition in South Carolina.

The tribe is part of the Caddoan Mississippian culture and thought to be an extension of Woodland period peoples who started inhabiting the area around 200 BC.

* The Daily Mississippian is the student-published newspaper of The University, established in 1911.

Although The Daily Mississippian ( DM ) is located on the Ole Miss campus, it is operated largely as an independent newspaper run by students.

Broad Top, located north of Breezewood, is a plateau of relatively flat-lying rocks that are stratigraphically higher, and thus younger ( Mississippian and Pennsylvanian ), than most of the other rocks within the county ( Cambrian through Devonian ).

Broad Top, located in the northeast corner of the county, is a plateau of relatively flat-lying rocks that are stratigraphically higher, and thus younger ( Mississippian and Pennsylvanian ), than most of the other rocks within the county.

A similar humpbacked figure is found in artifacts of the Mississippian culture of the U. S. southeast.

Archaeologists have speculated that Red Horn is a mythic figure in Mississippian art, represented on a number of Southeastern Ceremonial Complex ( SECC ) artifacts.

A mound similar to others across North Georgia ( including the famous Etowah Indian Mounds ) is located about one mile ( 1. 6 km ) east of Dillard, Georgia and is likely a remnant of an earlier mound-building Native American culture known as the Mississippian culture.

These characteristics are very similar to what is known about the prehistoric Mississippian Culture who occupied the Etowah Mounds village.

Cave Spring is well known for the natural wonders of the cave and spring site where native Indians came to the area ( both Cherokee and earlier Mississippian culture ).

This is an extensive prehistoric Mississippian culture urban complex located to the north in present-day Collinsville in Madison County.

The modern day city of Wickliffe is home to a Mississippian culture village now known only as Wickliffe mounds.

The city is located at the eastern end of Kentucky's " Mississippian Plateau " ( or " Pennyroyal "); however, the micropolitan area extends eastward into the " Appalachian Plateau " ( or " Eastern Kentucky Coalfields "), and northward to Kentucky's " Outer Bluegrass " region.

The Alibamu and the Coushatta, who lived on the opposite side the river, were descended from the Mississippian culture, which had built massive earthwork mounds as part of their society about 950 – 1250 AD.

Mississippian culture peoples built massive earthwork mounds along the Ouachita River beginning about 1000 CE.

The historic Creek peoples in this area are believed to have descended from the Mississippian culture, which flourished throughout the Mississippi and Ohio river valleys and the Southeast from about 1000 to 1450.

Mississippian culture peoples built massive earthwork mounds along the Ouachita River beginning about 1000 AD.

The town was named for the prehistoric monumental earthwork mounds in the area, likely built by the Mississippian culture about 1000 CE.

It was built by the Mississippian culture, which reached its peak in the region about AD 1100 – 1200 at the nearby major center of Cahokia, a designated UNESCO World Heritage Site within the present-day boundaries of Collinsville.

For instance, the Mississippian culture, reaching a peak about 1150 at Cahokia in present-day Illinois, had sites throughout the Mississippi and Ohio river valleys, and into the Southeast.

They are effigy and geometric mounds, different from the platform mounds at nearby Aztalan State Park, built by peoples of the Mississippian culture, which reached its peak about 1300 CE, had settlements throughout the Mississippi Valley and its tributaries, extending from central Illinois northward to the Great Lakes and also to the Southeastern United States.

By then end of the Late Woodland period, about 1000, the Miller culture area was absorbed into the succeeding Mississippian culture.

Likely built by the Mississippian culture, which rose about 1000 CE on the Mississippi and its tributaries, this mound was reported in use as late as 1540 by the Spanish explorer Hernando de Soto.

Mound building at this location began with the Emergent Mississippian cultural period, about the 9th century CE.

In the Big Horn Mountains the Tongue flows in its mountain canyon of Madison Limestone, which was deposited during Early to Middle Mississippian time, about 359 to 326 million years ago.

The earliest certain coleoids are known from the Mississippian sub-period of the Carboniferous Period, about 330 million years ago.

Remaining natural hot springsThe exposed rock types in the vicinity of the thermal springs are sedimentary rocks of Mississippian to Ordovician age, with the exception of younger igneous rocks ( Cretaceous age ) exposed in two small areas about 6 and southeast of the thermal springs ( Potash Sulphur Spring and Magnet Cove, respectively ), and in many small dikes and sills.

The site was inhabited during the Early Mississippian period from about 1000 to 1450 CE.

Chronologically this area became Mississippianized later than the Middle Mississippian area ( about 1000 CE as compared to 800 CE ) to its northwest and is believed that the peoples of this area adopted Mississippian traits from their northwestern neighbors.

Wickliffe Mounds ( 15 BA 4 ) is a prehistoric, Mississippian culture archaeological site located in Ballard County, Kentucky, just outside the town of Wickliffe, about three miles from the confluence of the Ohio and Mississippi rivers.

Construction of Monks Mound by the Mississippian culture began about 900 – 950 CE, on a site which had already been occupied by buildings.

It may have been an older iconograph from the large Mississippian culture city of Cahokia, which began developing about 900 CE.

The placoderms, a group of jawed fishes, appeared by the beginning of the Devonian, about 416 million years ago, and became extinct at the end of the Devonian or the beginning of the Mississippian ( Carboniferous ), about 360 million years ago.
