Oil was first produced from the Tinsley Field from the Late Cretaceous and the state had already produced over one billion barrels by 1970. A few wells were drilled as much as 20,000 feet deep.
The chiefdoms of this period collapsed about 1450, possibly because of drought, and a new group emerged to characterize the Late Mississippian period from 1475 to 1600, by which time a European presence in the United States had begun to impact the Mississippian peoples.
