Bones found in a Northumberland garden could form part of an unmarked historical burial site, police say.
Since the initial discovery of a jaw bone on Saturday, more bones and a human skull have been unearthed.
Police are working with experts from Northumberland County Council's archaeological department.
They say a medieval village used to exist at the site, and the bones' positioning - laid east to west - are consistent with a Christian burial.
The skull, which was found on Tuesday, has been sent away for carbon dating tests.
The remains were first discovered by a member of the public on Saturday afternoon in the Fenwick area, between Matfen and Stamfordham.
