Mounted Cleoniceras Ammonite 18cm
Mounted Cleoniceras Ammonite, fossil for sale from Madagascar. A high quality Cleoniceras ammonite mounted on a marble base, beautifully polished to reveal its rich golden brown calcites and amazing suture patterns, the mouth has also been expertly prepared out to the sutures. This 18cm diameter ammonite has had its original shell ground off to reveal the calcite replacement which has occurred over 120 million years. Water dissolves the original hard parts of the ammonite shell and replaces it with mineral matter in a very slow process. This beautiful rich coloured fossil is of a very high grade and very tactile, perfect for a collector or just something beautiful to own. It comes from the north west coast of Madagascar in the jungles of Mahajanga. It is from the Cretaceous period and comes complete with display stand.
