Stone Age finds discovered by chance off the North-East coast that rocked the world of archaeologists will be on show tomorrow.

Divers have uncovered two settlements under the sea off the coast of Tynemouth, dating back to up to 10,000 years.

They were once on dry land, but were gradually submerged as the sea level rose at the end of the last Ice Age.

The site, discovered accidentally by a Newcastle University team during a training scuba dive is only the second such Mesolithic settlement to be discovered in the UK.

At depths of up to eight metres, they recovered flints, arrowheads and rough hewn tools thought to be the first proof of a "prehistoric Atlantis" submerged off the North-East coast.

Mesolithic people lived in the Middle Stone Age, the era between the end of the last Ice Age 10,000 years ago, until the start of the agricultural revolution 5,000 years ago.

The first finds will be on show at an open day in the university's Dove Marine Laboratory, from 1.30pm to 4.30pm, as part of the Heritage Open Days in the region.
