The Marksville culture was an archaeological culture in the lower Lower Mississippi valley, Yazoo valley, and Tensas valley areas of present-day Louisiana, Mississippi, Arkansas,[1] and extended eastward along the Gulf Coast to the Mobile Bay area,[2] from 100 BCE to 400 CE. This culture takes its name from the Marksville Prehistoric Indian Site in Avoyelles Parish, Louisiana. Marksville Culture was contemporaneous with the Hopewell cultures within present-day Ohio and Illinois. It evolved from the earlier Tchefuncte culture and into the Baytown and Troyville cultures,[3] and later the Coles Creek and Plum Bayou cultures. It is considered ancestral to the historic Natchez and Taensa peoples.[4]
