Experts believe they have located Britain's own ‘Atlantis’ after evidence of two stone age settlements were found in the North Sea.
Two stone artefacts were found on the banks of a submerged ancient river which could be over 10,000 years old.
It is the first time an archaeological expedition has found ancient artefacts so deep into the sea.
The stone items were found in the North Sea close to the village of Blakeney in Norfolk.
Archeologists from the UK and Belgium worked together and travelled 25 miles north of the village to uncover the items.
The experts believe the artefacts are evidence of two settlements which once existed thousands of years ago.
Comparisons to Atlantis have been made because the mythical island state was believed to have sunk in the Atlantic Ocean.
Ancient Greeks believed that the city of Athens repelled an attack from Atlantis which was then submerged after the fictional island fell out of favour with the gods.

Fishermen in the North Sea have been known to find historically significant items but the seabeds these items come from have never been assessed by archaeologists.
The area near the Norfolk coast was targeted because scientists used their knowledge of what Stone Age settlements were like when on land.
The amazing findings were located when the scientists took sedimentary samples in the area.
However, the experts also believe they may have discovered why humans in the Stone Age were so attracted to the areas which were submerged into the sea around 6000 BC.
Before they drowned, the settlements likely existed for a long period of time between 8200 and 7700 BC.
Environmental evidence found at the site taken from pollen and other sources suggests the location was a huge landscape of land and animals.
This type of area would have been ideal for Stone Age settlers who relied on fishing and hunting for survival.
Further evidence found nearby suggests there were resources which allowed the prehistoric people living there to make flint for their tools.
It is even thought that the two settlements may have been bases for the making of tools.
This was speculated because one of the artefacts found in the North Sea was a large stone hammer which would have been ideal for toolmaking.
The other item found was a two millimetre thick flake of flint which might have been cut off when a tool was being made.
After the significant findings, it has been decided to further investigate the area for any other historical treasure buried there.
A mini submarine will be sent to the sea bed and collect any interesting items.
Divers may also be sent down the 32-metre distance to explore what the area looks like deep under water.
When the Ice Age ended lots of ice melted caused the sea level to rise and it is thought this is when the settlements were submerged underwater.
The investigations could reveal more about what life was like in Stone Age Britain and how our distant ancestors lived.
