DNA testing is to be carried out in Dublin on a human skull discovered in West Cork.
The partial human remains were found in a plastic bag at a rented house near Eyeries at around 3pm on Friday.
A couple carrying out clearance work discovered the skull in the back garden.
Southern correspondent with the Irish Times Barry Roche said Gardaí think the skull could be decades old.
"Gardaí are of the view that it's at least 20-years-old and maybe longer, it may go back to the early naughties, may go back to the '90s, perhaps even to the late '80s," he said.
"The house was previously owned by a Dutch couple and they had rented their caravan, so various people over the years.
"That's one avenue of inquiry they are investigating."
