One of the oldest living trees in the world has been discovered in a North America swampland that is at least 2,624-years-old.
The bald cypress, also the oldest-known wetland tree species, was found in North Carolina forest.
Scientists established its age using carbon dating and tree-ring measurements which also revealed ancient climate patterns.
The species is however under threat from illegal logging as well as water pollution, and rising sea levels as a result of climate change, scientists warned.

Geologists from the University of Arkansas discovered the ancient trees back in 2017 while studying tree rings in North Carolina's Black River swampland.
Using tree ring dating and radiocarbon dating they were able to establish that the bald cypress trees, also known as Taxodium distichum make up one of the oldest non-clonal, sexually reproducing trees in the world.

Professor David Stahle, who made the discoveries, has been working in the 16,000 acres Black River Preserve since 1985.
In 1988, he catalogued bald cypress trees that was 1,700 years old.
Professor Stahle said: 'It is exceedingly unusual to see an old-growth stand of trees along the whole length of a river like what he observed.
'Bald cypress are valuable for timber and they have been heavily logged.
'Way less than 1 percent of the original virgin bald cypress forests have survived.'
