The area known as Doggerland is a real-life Atlantis from a time when the British Isles were neither British nor Isles. The land occupied a great portion of where the waters of the North Sea extend nowadays.After the last major Ice Age, some 12,000 years ago, the area got flooded over time by the rising sea levels.Map showing hypothetical extent of Doggerland (c. 10,000 BC), which provided a land bridge between Great Britain and continental Europe.

Photo by staticgirl CC BY 2.0Named after the Dogger Bank, Doggerland was first mentioned in a book A Story of the Stone Age by H.G. Wells, written in the late 19th century. The book suggested the existence of a prehistoric region that fused Britain’s east coast with the European mainland.Archaeologists at the University of Bradford are working on a huge project to reconstruct the ancient Doggerland landscape which is now underneath the sea.They are aiming to produce a 3D chart of the landscape with the help of seabed mapping data gathered by energy companies.The red line marks Dogger Bank, which is most likely a moraine formed in the Pleistocene.In the meantime, scientists wait on core sediment samples to extract DNA fragments from plants and animals, so that we can learn more about the flora and fauna that once existed.Before the last glacial period, the vast piece of land that connected Europe and Britain consisted of a diverse mix of gentle hills, swampland, and dense forests.With the lessening of the huge weight of ice, melting water got locked away which caused the land to tilt in an isostatic adjustment.Early Holocene landscape features mapped by the North Sea Palaeolandscapes Project.

It was also a very important land bridge between Europe and Britain.According to the evidence gathered, scientists believe that the Doggerlanders were nomadic hunter-gatherers who migrated with the season. They lived on hunting, fishing, and gathering foods such as berries, nuts, and mushrooms.Map of Doggerbank, 1867.For hundreds of years, fishermen have pulled up all kinds of finds in their nets in the area off the coast of Dogger Bank.In 1931, there was a famous discovery of a lump of peat which contained an ornate barbed antler point used for harpooning fish. It was hauled up near the Ower Bank, 25 miles off the English coast.Woolly mammoth skull discovered by fishermen in the North Sea, at the Celtic and Prehistoric Museum, Ireland.

That triggered a tsunami in the North Atlantic Ocean with waves up to 17 feet in height.Map showing hypothetical extent of Doggerland from Weichselian glaciation until the current situation.

The glacial melt once caused the destruction of the home of the Mesolithic people as well.
