This North American culture lasted for about 1,000 years.  I wonder if the USA will do so, sometimes, geez!

CHILLICOTHE — As word of new evidence emerges that Chillicothe’s place in history goes back to the first century of the Common Era, at least one state historian is hoping people understand the importance of the discovery.

Ohio Historical Society archaeologists, in partnership with researchers from the private Cultural Resource Management firm Gray & Pape and Ohio State University, conducted radiocarbon testing on small pieces of bark and fabric excavated from the Adena Mound in 1901.

The bark produced dates of around A.D. 40, whereas the textile gave a date of 140 B.C. The new dates will be reported in an article in the February issue of the Midcontinental Journal of Archaeology.
