Deep underneath the North Sea, researchers have actually found a fossilized forest that might hold traces of ancient early people who lived there around 10,000 years back, prior to the land slipped underneath the waves a couple of thousand years later on.
The discovery offers the scientists brand-new hope in their look for “lost” Middle Stone Age– or Mesolithic– settlements of hunter-gatherers, due to the fact that the discover programs that they have actually discovered a specific kind of exposed ancient landscape.
The researchers took sediment samples from the immersed fossilized forest throughout their 11- day trip in the North Sea aboard the research study ship Recreational Vehicle Belgica, in the Doggerland area referred to as Brown Bank or Brown Ridge. The researchers state they are specific they are close to discovering traces of an ancient human settlement in the immersed lands. [See Images of a Treasure Trove Found Beneath North Sea]
” We are definitely dead sure that we are really near a settlement,” stated archaeologist Vincent Gaffney of Bradford University in the U.K., among the task leaders. “The varieties of artifacts traditionally from that area inform us there is something there.”
” We have actually now recognized the locations where the Mesolithic land surface area is close to the surface area [of the seafloor],” he stated. “So we can utilize the dredges or grabs to get bigger samples of whatever that surface area is.”
The researchers now prepare to review the Brown Bank location on a Dutch research study ship in the fall, with much heavier dredging devices that will let them take more samples from the immersed fossilized forest, Gaffney stated.
Below the waves
Doggerland when covered countless square miles in between what is now the east coast of England and the European mainland. It is called after the neighboring Dogger Bank, a shallow area often visited in the Middle Ages by Dutch fishing boats called doggers.
The area was exposed as the northern icecap declined at the end of the last Glacial epoch, about 12,000 years back, and ended up being a large, forested plain, occupied by herds of animals and neighborhoods of early human hunter-gatherers.
However the land ended up being immersed as water level continued to increase; Doggerland slipped underneath the North Sea about 8,000 years back– leaving Britain as a group of islands off of the coast of Europe.
For many years, the so-called Brown Bank location in between England and the Netherlands has actually quit many historical discovers to fishing boats and digs up, consisting of ancient human bones, flint tools, spear points and even carved-bone art work
A location as big as Doggerland would have included several human hunter-gatherer groups, amounting to countless individuals, Gaffney informed Live Science.
The exposed undersea landscape of Brown Bank is the very best chance for discovering any of them, he stated.
Countless sediment cores were drawn from North Sea in the past for various factors, consisting of overseas wind farms, Gaffney stated, however the most recent exploration was “an opportunity to focus on the finding of human settlements in the center of the North Sea.”
Searching for the Stone Age
Throughout the most recent exploration, the scientists utilized specific dredges to get samples from Brown Bank, however the tough scared wood of the immersed, fossilized forest made that tough, and much heavier dredges will be utilized the next time that the scientists check out the location by ship.

Some samples had actually likewise revealed layers of compressed peat simply listed below the seafloor, which suggested previous wetlands that might have offered almost ideal conditions for early human habitation. “The maximum locations are wetlands, where there [area] water, birds, fish and shellfish,” Gaffney stated.
The sediment samples from the most recent exploration are now being studied; the analysis will take a number of months, he stated. Information from the exploration will likewise be utilized to additional upgrade historical maps of immersed Doggerland, which have actually been prepared from seismic studies and sediment samples over a number of years, Gaffney stated.
The existing maps of Doggerland reveal the now-submerged areas of what when were shorelines, rivers, lakes and wetlands– even a huge saltmarsh. “I is a huge landscape below the sea,” the scientists stated,
However the maps likewise reveal that parts of the immersed lands are entirely covered by reasonably contemporary sediments, disposed by a few of the biggest rivers in Europe, such as the Rhine and the Meuse, Gaffney stated.
Locations like Brown Bank were particularly essential to archaeologists, due to the fact that the Stone Age landscape there was exposed, or within a couple of inches of the surface area of the seafloor.
The scientists now hope that their future explorations to Brown Bank yield definitive indications of human settlement there– such as ancient human bones and even human-made artifacts. “We are really near discovering this settlement,” Gaffney stated. “It exists, we understand it is– we require simply that bit of luck and great weather condition to arrive.”
The group strategy to review the location aboard a Dutch research study ship in the fall, with much heavier dredging devices that will help with taking more samples from the immersed landscape, Gaffney stated.
