The oldest known forms of life captured in stone! The Tortuga Fossil Vessel in Soumon (195)) features real marine life fossils in blocks of stone carved into vessel sinks. Truly one of a kind and unique! The creatures embedded in the stone, known as ammonites and orthoceras, lived in abundance in a primitive sea. Evidence of this life-filled sea has been preserved through the ages beneath the sands of the Sahara Desert.
