Ammonite Douvilleiceras 7.4cm
Douvilleiceras Ammonite, fossil for sale from Madagascar, beautifully polished to reveal its rich golden brown calcites and wonderful suture patterns. This 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 fabulous rich coloured fossil is 7.4cm at its widest diameter and 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.
