This very attractive 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 8 x 7 x 6 cm. It is very stabile and solid.
Rarely offered fossil without any manipulations!
Museum piece!
