8 million year old trees found in Hungary, preseved

Archaeologists found the 16 preserved trunks in an open cast coal mine in the north-eastern city of Bukkabrany.

The specimens were preserved intact while most of the forest turned to coal thanks to a casing of sand, which was perhaps the result of a sandstorm.

It is hoped the trees may offer experts a valuable insight into Earth's climate eight million years ago.

The massive trunks are of a species known as swamp cypresses, which grew for 200-300 years.
