  2. In a beach near Galaxidi, in Greece, i found some grey fossils on rocks with layers, just like the stromatolites. I believe that these fossils are members of Francevillian biota, witch includes the earliest multicellular organisms that was found in Gabon. These are the reasons that make me think that these fossils are from the Francevillian biota; 1.The fossils have got the same thickness with these that were found in Gabon; 6 mm. 2. In the past, one part of Eurasia (probably Greece) was next to Gabon in the Paleoproterozoic era, when the Francevillian biota appeared. 3. Its rock has got the same color with these from Gabon. Probably are made from the same minerals. 4. The fossils have got the same forms with the members of the Francevillian biota.
