Prof Eileen Murphy of the Centre of Community Archaeology at QUB said the find was "mind-blowing".
"With archaeology you never know what you're going to find. We've actually been able to push the date of this site back from the 400 years we were looking for to about 8,000 or 9,000 years ago, to the time of Ireland's first settlers in the early Mesolithic."
