A leaf that fell from an elm tree more than 6,000 years ago was discovered intact by archaeologists in the United Kingdom.
Scientists found the leaf -- along with a selection of Stone Age tools and pottery -- when they were clearing a piece of land outside of Blackpool along the coast of northern England.
Lead archaeologist Fraser Brown told The Daily Mail that the finds were of national significance.
"We have found extensive deposits of peat and marine clays which have helped preserve ancient plant remains and which yield information on the local vegetation, water, climate, and human activity," he explained to the British publication.
"We've also found pottery, stone tools and charred remains providing direct evidence for Mesolithic hunter-gatherers foraging, and possibly camping, at the water's edge and later on, Neolithic and Bronze Age farmers living on the fringes of a salt marsh," Brown added.
The haul of items found at the site reportedly also includes wood, leaves, hazelnuts and ancient pollen.
