Stone Age megastructure found submerged in the Baltic Sea wasn’t formed by nature, scientists say

Stone Age hunter-gatherers hunted reindeer more than 10,000 years ago , a German study finds.

A wall made of 1,670 stones was found in the Baltic Sea , about 6 miles off the coast of Rerik , Germany .

The wall was likely built by Stone Age communities to hunt reindeers, researchers say.

It could be the first Stone Age hunting structure in the region, they say.

The Lake Huron wall’s construction and location, which includes a lakeshore to one side, is most similar to the Baltic Sea wall's.

The scientists continue their investigation in the Baltic using sonar and sounding devices.

Other undiscovered treasures at the bottom of the Baltic could potentially shed more light on ancient hunter-gatherer communities.
