Scope of the project
The scope of the project was to record and document the existence of the underwater fossil concentrations of petrified trunks of palm trees, pine trees and wide-leaf trees in an area which was systematically surveyed in the past few years. A technical report prepared suggesting the delimitation of an extensive area for the protection of the fossils from human activity (net fishing, anchoring etc) in order the authorities to take further actions.
The Geopark/Fossilized Forest  is located in the seaside area of Agia Marina, SE of Agios Nikolaos Village in Laconia, Greece.
The singularity of this Geopark lies in the process of the fossilization, which is unique, at least, in Greece.
Elsewhere in Greece, like the petrified forest parks in Lesvos Island, Evros etc., the sample analysis showed that the fossils were “Pyritized” or “Mummified” due to volcanic eruptions. Agia Marina’s Geopark trunk sample analysis revealed that the fossilization process was by “Permineralization” (The forest submerged million years ago. When the seawater level raised, the trees were covered by lime ).
The fossils are estimated to be 2-10 million years old.
Scattered blowholes around the sediment rocks, where once tree trunks existed.
Impressive fossilized roots.
Underwater Fossilized Forest
What it is not widely known, is that in the area, there are multitudinous submerged fossilized trunks, that surprisingly in some cases are even larger compared to the existing ones in land.
There is also another consideration to be mentioned  based on which some of the depicted formations could be “carbonate chimney structures” which in principal is also a quite rare geological phenomenon .
