Gold coloured ammonite
Beautiful gold / yellow pyrite ammonites from Buttenheim Germany
These ammonites are found in Germany in the town of Buttenheim near Bamberg. The beautiful golden glow of these ammonites is immediately noticeable. This color is caused by the iron ore pyrite. During the fossilization process the ammonite is not petrified but 'pyritised.
These ammonites belongs to the Pleuroceras Spinatum family that lived between 190 and 183 million years ago. This species lived mainly in the area where Europe is now days. Ammonites were a group of marine mollusks where the current squid also belongs to. Now days squids have their shell inside but the Ammonites had their shell outside their body, just like snails.
Chambers of an Ammonite
The Ammonites house consists of chambers. Whenever the hard case was too small for the animal it built a new room that was larger than the previous one. The animal always lived in the last build room. The empty rooms could be filled with water or gas. Like that the ammonite could travel between the surface and the bottom of the sea.
