'Unique' petrified tree up to 20m years old found intact in Lesbos

Discovery of 19.5-metre tree with roots, branches and leaves is unprecedented, say experts

First came the tree, all 19.5 metres of it, with roots and branches and leaves. Then, weeks later, the discovery of 150 fossilised logs, one on top of the other, a short distance away.

Nikolas Zouros, a professor of geology at the University of the Aegean, couldn't believe his luck. In 25 years of excavating the petrified forest of Lesbos, he had unearthed nothing like it.
