Ammonite Lytoceras 9.4cm
Excellent Lytoceras Ammonite fossil from Madagascasr beautifully polished to reveal its rich calcites and striking suture patterns. The 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 9.4cm diameter 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 east coast of Madagascar in the jungles of Mahajanga. It is from the Cretaceous period and comes complete with display stand.
