This Stromatholithes stone comes from the Oligocene age of Gannat in France.
Due to embedding in clayey rock the fossil was fossilized beautifully three-dimensional (cauliflower shaped).
The piece is unbroken, it measures about 11 x 11 x 10 cm. It is very stabile and solid. It have been cut and polished to allow a nice view into the inner side of these starnge creatures
Rarely offered fossil without any manipulations!
