Parco Naturale Regionale del Beigua

In the fossil-bearing beds in the area of S. Giustina, a rich terrestrial flora was found consisting of tree trunks and many leaves. Surfacing from the Sansobbia stream bed, remains of carbonified trunks, some of which of significant size, are clearly visible. Leaves are preserved as detailed imprints, with or without carbon film. The fossil terrestrial flora of S.Giustina, consisting of pteridophita, gymnospermae and angyospermae (Monocotyledons and dicotyledons) is very rich, both for the number of species and the number of specimens in each species.
