"A team from the University of Newcastle upon Tyne in northeast England say they found flint artifacts including tools and arrowheads off the coast near Tynemouth during a training session to prepare them for dive searches elsewhere.

They say the items pinpoint two sites dating as far back as 10,000 years ago which would once have been on dry land but were gradually submerged as sea levels rose after the end of the last Ice Age."

If they keep looking, the might find some non-stone age settlements from back then....
