An underwater stone wall discovered in the Baltic Sea near Germany was built about 11,000 years ago for hunting reindeer when the location was dry land, a new study indicates.
But changing sea levels caused by melting ice sheets after the last ice age flooded the area about 8,500 years ago, along with other parts of the modern Baltic and the "Doggerland" region that joined Britain and the European continent.Hunting wallScientists detected the wall almost by accident in 2021, during a boat trip into the Bay of Mecklenburg to teach marine geophysical techniques to students.
Geersen and Marcel Bradtmöller, a prehistorian at the University of Rostock in Germany, are the co-lead authors of the study about the discovery, published Monday in the journal PNAS. As well as mapping the wall, the researchers hope to find buried artifacts along its length that could reveal more about the wall's origins and use. They suggested that parts of the wall could have been"blinds" where people tasked with killing the animals could have hidden so as not to scare away a panicked herd.
