Florida. It is possibly a mammoth bone, etched with a profile of walking mammoth; it dates to 11,000 BCE. Poverty Point culture The Poverty Point culture inhabited portions of the state of Louisiana from 2000–1000 BCE during the Archaic period. Many objects excavated at Poverty Point sites were made of materials that originated in distant places, indicating that the people were part of an extensive trading culture. Such items include chipped stone projectile points and tools; ground stone plummets, gorgets and vessels; and shell and stone beads. Stone tools found at Poverty Point were made from raw materials that can be traced to the relatively nearby Ouachita and Ozark mountains, as well as others from the more distant Ohio and Tennessee River valleys. Vessels were made from soapstone which came from the Appalachian foothills of Alabama and Georgia. Hand-modeled lowly fired clay objects occur in a variety of shapes including anthropomorphic figurines and cooking balls. Mississippian culture Mississippian cultures flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 CE to 1500 CE, varying regionally. After adopting maize agriculture the Mississippian culture became fully agrarian, as opposed to the preceding Woodland cultures that supplemented hunting and gathering with limited horticulture. Mississippian peoples often built platform mounds. They refined their ceramic techniques and often used ground mussel shell as a tempering agent. Many were involved with the Southeastern Ceremonial Complex, a multi-regional and multi-linguistic religious and trade network that marked the southeastern part of the Mississippian Ideological Interaction Sphere. Information about Southeastern Ceremonial Complex primary comes from archaeology and the study of the elaborate artworks left behind by its participants, including elaborate pottery, conch shell gorgets and cups, stone statuary, and Long-nosed god maskettes. The Calusa peoples, of southern Florida, carved and painted wood in exquisite depictions of animals. By the time of European contact the Mississippian societies were already experiencing severe social stress. Some major centers had already been abandoned. With social upsets and diseases unknowingly introduced by Europeans many of the societies collapsed and ceased to practice a Mississippian lifestyle, with an exception being the Natchez people of Mississippi and Louisiana. Other tribes descended from Mississippian cultures include the Alabama, Biloxi, Caddo, Choctaw, Muscogee Creek, Tunica, and many other southeastern peoples. Post-European contact During the Indian Removal era of the 1830s, most southeastern tribes were forcibly relocated to Indian Territory west of the Mississippi
