Research indicates that prehistoric animals that become pyritized, such as trilobites and ammonites, were rapidly buried under ocean sediments that were low in organic matter.

 

In this case there would not be a lot of decaying material present. Another important condition was anaerobic seawater – the water was low in dissolved oxygen.

One of the final conditions for pyritization to occur is to have large numbers of sulphate reducing bacteria (they live in oxygen deficient water) and a high concentration of reactive iron. The bacteria change the sulphates into sulphides which can then diffuse with the iron into the ammonite or other organisms forming our spectacular fossils.
