An ancient tree trunk believed to date back thousands of years has been discovered during work in a city park.

A glacial rock believed to have been washed down to the Aberdeen park during the ice age was also found by contractors.

Aberdeen City Council said the rock found near a sports pitch in Seaton Park is not native to the area, while it is believed the tree trunk had been deposited there when the park was still part of the River Don.

Experts at Aberdeen University have now been asked to determine what species and how old the tree is.

Councillor Jean Morrison, housing and infrastructure vice-convener, said: "It's been great to see the work come together at Seaton Park and then for these two discoveries to have been made makes it even more exciting.

"We're looking forward to seeing the completed Seaton Park Wetlands and I'm sure generations of Aberdonians to come will appreciate the area along with the interesting finds of the glacial rock and the huge tree trunk under the ground."

The ancient items were discovered by workers carrying out the £90,000 wetlands project at the park, which will feature a flooded grassland turned into a nature reserve.
