The trees were part of land that once stretched all the way to Germany.
Divers Dawn Watson and Rob Spray, from volunteer group Seasearch, were studying marine life just 300m from the shore at Cley when they made the discovery.
“I set off north and I’d been swimming for about 15 minutes before I came to anything,” Ms Watson, 45, told the BBC.
“It was a great wave of black stuff in front of me and it took me a while to work out what it was but it was just wood, shaped like a wave.
“To start with I thought it was a piece of wreck because it looked like a piece of hull…it’s the remains of a forest, probably oak trees that have been knocked flat, presumably by outwash from a glacier.”
Some of the wood was compressed but whole tree trunks with branches could be seen, with starfish and crabs making knots in the wood their home.
The preserved forest was part of the former landmass known as Doggerland, which connected the UK to mainland Europe until after the last Ice Age, when it was flooded by rising sea levels.
Boats have salvaged mammoth and lion fossils from the sea, as well as prehistoric tools and weapons, but scientists had no idea the forest could still be seen so close to the Norfolk shore.
Doggerland was once so vast that hunter-gatherers who could have walked to Germany across its land mass, the BBC reported.
“At one time it would have been a full-blown Tolkien-style forest, stretching for hundreds of miles,” Mr Spray told the Eastern Daily Press.
“It would have grown and grown and in those days there would have been no one to fell it, so the forest would have been massive.”
Last winter’s storm also revealed prehistoric forests off the west coast of Wales and in Cornwall.
Gnarled tree stumps and roots, believed to be dating from the Bronze Age, have become visible for the first time after peat was washed away on the shore near the village of Borth, Ceredigion.
The heavy winds and rain also shifted swathes shingle and sand on Cornish beaches, to reveal trunks of oak, beech and pine near Penzance in Mount's Bay.

Tallet and colleagues also found 10 very well-preserved papyri among hundreds of fragments. The documents, which are proving difficult to reassemble, are the oldest papyri ever found in Egypt. One fragment is a diary written by Merrer, an Old Kingdom official involved in the building of the Great Pyramid. Though actual details of the pyramid's construction are scarce, Tallet says, "the journal provides a precise account for every working day."
A well-published experiment, in such a way that many people
could share in the knowledge and insights learnt from this activity, was the
building of a Stone Age house in Denmark in 1958 by Hans-Ole Hansen. He
describes the successes and setbacks in an accessible, lively manner. Such
activities, based on trial and error, cannot follow a planned script, because
many details are unknown from the drawing table. They are more about gaining
experiences and counting how much material and how much time goes where (the
way `we' build it). The fact is, 50 years later, we still meet surprises each
time we build a `prehistoric' house somewhere; surprises that mean we need to
improvise and solve problems on the spot. For example, one needs to have tried
cutting trees with both a stone axe and a steel axe before you can compare them
in usability. It takes some experience in using both kinds, as they need to be

The magnitude of raw material transfers between the Auvergne
sites and sources 250-300km further north illustrates a case of continuity in
mobility patterns across the Middle/Upper Palaeolithic divide, which is
consistent with the cultural ecological paradigm. Considered in a
techno-economic perspective, these transfers also reinforce previously stated
