Coastal erosion exposes ancient trees on Yorkshire beach
The blackened timbers can be seen at Tunstall, near Withernsea, close to the Sand Le Mere holiday park, where they have been preserved for millennia in clay.
Dr Peter Halkon, senior lecturer in archaeology at Hull University, said they were likely to be the remains of a forest submerged by a tidal surge - perhaps like the one in 2013 - and sea level rise in the Bronze Age.

But the only way to be sure was through further investigation, involving radiocarbon and tree-ring dating.
Dr Halkon said: “It provides evidence of sea level rise and how it needs to be taken seriously.
"It also reminds people that one of the fastest eroding coastlines in Europe is the North Sea coast of England, particularly Holderness because of the softer nature of its geological deposits.”

In north Lincolnshire 15 villages in total were flooded and some 255 homes.
In South Ferriby residents reported hearing an eerie sound like a waterfall as water rushed in from the Humber.
In Hull drinkers in a pub told how they saw their own vehicles float away before retreating upstairs after a torrent of water rushed in from the Humber, crossing the A63 and into Ferensway.

He thought these were the remains of a lake dwelling.
Hornsea Mere is now the only surviving example of the meres in Holderness - although traces can be seen in peaty streaks in several areas in the cliff face along the eroding coastline.
