A team of researchers headed by Lund University’s Professor Dan Hammarlund has uncovered an exceptionally well-preserved Mesolithic site off the Baltic Sea coast at Haväng in south-eastern Sweden. They believe the location was a lagoon environment where ancient humans lived during parts of the year. “The submerged landscape at Haväng is unique, as the excellent preservation of both natural and cultural objects and the longevity of the site are rarely seen in other submerged Mesolithic sites,” Prof. Hammarlund and co-authors said. Changes in the sea level have allowed the findings to be preserved deep below the sea surface. “Organic-rich sediment ridges with abundant wood remains and archaeological artifacts extend 3 km from the modern coast to depths of at least 20 m below the present sea level,”…
