The Dunarobba fossil forest nearby Avigliano Umbro, has been discovered in the 70s, but the work to bring it up to surface are not yet finished. All the trees belong to a family of sequoia which used to be present in this part of italy more than one million years ago. The particularity with this forest is that the trees lay in vertical position and not horizantally as it is the case for other fossil forests. This would confirm the theory that a flood could have overwhelmed the forest preserving it in the shape we admire today. The fossiles have enormous dimensions: 1.5 m in diameter and between 5 and 10 meters in high.
