Seven sites in Mississippi, Louisiana and Arkansas have been dated. For six sites (Terral Lewis, Poverty Point, Jaketown, Teoc Creek, Shoe Bayou, and Claiborne) the results are not inconsistent with contemporaneity; excluding Claiborne the average date is 1000 b.c., with an error limit in absolute terms of ± 200 years. The seventh site (Loggy Bayou), in which sherds and balls were found in association, gave a date some fifteen hundred years more recent.
