Additional information needed for carbon dating
Reported contextual information on where the sample was obtained. This date is not always referenced in the database due to the fact that it may not have been referenced in the publication.
Each record in the database should have a conventional radiocarbon age.
The Louisiana radiocarbon database that you will be searching today is based on the original Louisiana radiocarbon database published in 2001 (Mc Gimsey and Van der Koogh) and has been updated to include published radiocarbon dates from December 1999 onward.
One of the goals of the database, in addition to making the information more accessible to the public, is to keep the information as up-to-date as possible.
The earlier radiocarbon dates in this database were calculated using an estimated correction factor.
These dates will be represented with an asterisk (*) after the number in the correction factor field.
