Local archaeologist Ian Leitch believes the item dates from the Mesolithic period or middle stone age and was around 7,000 years old.
And he believes the finds significant in terms of the wider archaeology of the area. “The axe head from Culmore suggests that there may be a mesolithic site on or near to the find spot. It may have been dropped or lost by its owner while out hunting on land near the river.”
He added: “The stone axe head is made from mudstone, measures around six centimetres in size and is in quite good condition.”
Mr Leitch paid tribute to the finder for alerting him to the find. He added: “It is important that such an artefact is reported and properly recorded.”
