Doggerland is a name given by archaeologists and geologists to a former landmass in the southern North Sea that connected the island of Great Britain to mainland Europe during and after the last Ice Age, surviving until about 6,500 or 6,200 BCE, though gradually being swallowed by rising sea levels. Geological surveys have suggested that Doggerland was a large area of dry land that stretched from Britain`s east coast across to the present coast of the Netherlands and the western coasts of Germany and Denmark. Doggerland was probably a rich habitat with human habitation in the Mesolithic period.
