Pyritized Ammonite Nodule

Regular price £75.00

In their original mudstone matrix, these pyrite ammonites are captured in a nodule along with the ‘negative’ imprint of the ammonite. 

Although the amazing bright golden colour looks as though these fossils have been gilded, they are in fact entirely natural.

The distinctive and natural shimmer is down to the fossilisation process, which has led to the original material of the ammonite shell being replaced with a fine layer of the mineral Iron Pyrite.

From Untersturmig, Germany, of the species Pleuroceras Spinatum. Late Jurassic, circa 185 million years old. 

Measurements are approximate and the minimum size you should expect your fossil to be. Price includes a small display stand.   

Nodule 4.5cm x 4cm minimum
