Report on study of bones in Sutherland sand dune
Further analysis has been recommended of human bones found buried in a sand dune in Sutherland.
Guard Archaeology's report on last October's discovery at Farr has been uploaded onto to the Highland Historic Environment Record database.
The Glasgow-based archaeologists said it was unclear why the skeleton was incomplete and suggest animals, or other people, may have taken them.
The bones were found about 10m away from skeletal remains found in 2010.
A tenant farmer made the 2011 find after spotting bones in an eroding sand dune.
Northern Constabulary made the 2010 excavation and later handed over the bones to Highland Council's archaeology unit.
Guard Archaeology has recommended skeletal analysis and radiocarbon work to determine the sex and age of the bones found at Farr, near Bettyhill.
In the report, the archaeologists said: "The human remains retrieved from Farr by Bettyhill represent an incomplete inhumation, with some of the larger and many of the smaller bones missing.
"It is not possible to state with any certainty why so many bones are missing, although removal by animals or humans cannot be excluded."
