Hugely interesting.
I personally would not want to live before around 1950.
Chance is large I would die in the wars, from a childhood disease or later infection.
In fact, had I moved my exact life as it has been I would have died around 10 times
I found another report about that site, in Swedish. Excavated 2009 - 2011.
They think the skulls were placed there well after natural defleshing. No marks on the bone surfaces, no marks in the TMJ area.
They think it was some sort of ceremonial place.
8000 BC is very early for humans to permanently live in that area.
Close to the retreat of the glaciers, the landscape must have been still very raw.
And the human friendly coastline is underwater now.
They have found traces of several early Mesolithic sites in Öresund ( sea between Denmark and Sweden) and south of Sweden.
