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 about twice as long as the Pennsylvanian, but due to the large thickness of coal bearing deposits with Pennsylvanian ages in Europe and North America, the two subperiods were long thought to have been more or less equal.

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

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.

These tribes and earlier peoples, collectively known as the Mississippian culture, had long used the Trace for trade, so they likely used it with the Europeans.

Over 200 years passed and the Mississippian Indian culture disappeared, devastated by disease, but the Indian town named Chicasa which De Soto visited was probably the ancestral home of the Chickasaws who still lived in the area when Anglo-Americans began showing up.

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

While the Europeans also named the Cahokia Mounds site to the north after the Illini group, archeologists have determined that the earthwork mounds complex was built by the Mississippian culture, an earlier, potentially unrelated indigenous people.

The river is named after the Mississippian paramount chief Tuskaloosa, whose name meant Black Warrior in Muskogean.

A new Late Mississippian cultural group subsequently emerged and have been named by archeologists as the Caborn-Welborn culture.

The Mississippian way of life began to develop around the 10th century in the Mississippi River Valley ( for which it is named ).

* Old Town ( Franklin, Tennessee ) a location along the Natchez Trace named for the Mississippian mound complex there

The Mississippian way of life began to develop in the Mississippi River Valley ( for which it is named ).

The name of Aztalan, Wisconsin ( a Mississippian site ), was proposed by N. F. Hyer in 1837, because he thought it might have been Aztlán, following a suggested etymology of Aztatlan by Alexander von Humboldt.

The mounds at Ocmulgee were unusual because they were constructed more distant from each other than was typical of other Mississippian complexes.

The Burlington escarpment of Mississippian rocks, which in places is as much as 250 to.

The sedimentary rocks that compose both plateaus are of Mississippian and Pennsylvanian geological age, composed of near shore sediments washed westward from the old Appalachian Mountains.

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 underlying Ordovician rocks are overlain by disturbed Devonian and Mississippian rocks.

These wells did not find oil, but did indicate very thick sections of Mississippian and Pennsylvanian rocks.

The belemnoids ' origin lies within the bactritoid nautiloids, which date from the Devonian period ; well-formed belemnoid guards can be found in rocks dating from the Mississippian ( or Early Carboniferous ) onward through the Cretaceous.

The exposed rocks consist of the Devonian-Mississippian Rockwell Formation, underlying the Mississippian Purslane Sandstone.

The " mountains " are made up of sedimentary rocks ( mostly sandstone and shales, with a little conglomerate ) that were part of a lowland that collected sediments eroded from mountains to the southeast in Mississippian and Pennsylvanian geologic time.

Bruntál is a part of the region consisting foremost of sedimentary rocks formed during the Mississippian Epoch of the Carboniferous period.

The orogeny extensively deformed Paleozoic rocks of the Great Basin in Nevada and western Utah during Late Devonian and Early Mississippian time.

It consists of sedimentary rocks of Mississippian age ( 354 – 323 million years ago ) in Texas.
