Scientists: Stone Age Megastructure Discovered in Baltic Sea Not Formed by Nature

Three articles report on the discovery of an unusual stone structure located at the bottom of the Baltic Sea off Germany's coast. The structure, which is approximately 1 km long and consists of around 1,500 stones, was first discovered by geologists in autumn 2021. Researchers from various disciplines have concluded that this structure, which is aligned so regularly that a natural origin seems unlikely, was likely built by Stone Age hunter-gatherers around 11,000 years ago for hunting purposes, specifically reindeer. Another article suggests that the wall may be the oldest known megastructure built by humans in Europe and was possibly constructed on land next to a lake or marsh 10,000 years ago. The articles do not contradict each other significantly but differ slightly in the estimated age of the structure's construction.
