Stonehenge had a lot of Bag & Pin burials of ashes indicating that they were buried more often than not.
There is also Woodhenge so close to Durrington to take into account plus Odd things that don't yet seem to fit any pattern like the Cuckold Stone in the field next to Woodhenge.
The other stray Sarsen at Bulford, which incidentaly is intervisible with the Cuckold stone, had a ringed ditch and a burial around it.
God/dess know what the Cursus was about but it ends/starts so close to Woodhenge/Durrington that is seems to have had its place in the scheme of things.
