has been excavating a site on the island known as Vasagard. Vasagard was a large site surrounded by several impressive palisades.
excavation blog for the 2014 season at the site, when the digging focused on this burial trench ("System grave" in the plan.) Only scattered fragments of bone were found, and the trench showed evidence of having been redug several times. The excavators think it was used for temporary burial; corpses were placed in the ground until the flesh had rotted away, then the bones were removed for display in charnel houses or some such.
Fascinating. The enormous investment late Neolithic people made in religion, astronomy, and burial of the dead never ceases to amaze me.
