Doggerland (Great Britain)
Scientists believe a submarine landslide off the coast of Norway, the Storegga Slide, flooded coastal land surrounding Doggerland around 6200 BC.17
Before that catastrophe, Doggerland was made up of thick forests and marshland and was home to Mesolithic people who used it as a seasonal hunting ground.18 The people were flooded out of the area over time as glaciers and ice sheets began to melt.
Evidence of Doggerland was first discovered in the first half of the 20th century, and in the 1990s fishermen came across animal tusks and ancient tools. Scientists and archaeologists have since explored the area thoroughly, discovering peat and fossilized forests beneath the seafloor.
