In the Dutch natural park in Leersumse Field (Utrecht) remains are found of an ancient forest of at least 1.2 million years old.
The forest was accidentally discovered while digging a fire pit, according to Dutch State forest management.
At 29 meters depth State forest management stumbled on a 20 cm thick layer of fossilized wood.
After analyzing the pollen grains by TNO showed that the remains are of an ancient forest.
The forest includes spruces, hornbeam, lime and wing nut trees which comes from a warmer time period than today.
Some trees are now only found in a Mediterranean climate, which would not survive here.
