7.3" Sliced Ammonite (Speetoniceras) With Druzy Pyrite

 
 
 
This is an absolutely beautiful, 7.3" wide Speetoniceras versicolor ammonite fossil from the Lower Cretaceous deposits of the Volga River in Russia. It has been sliced in half, and polished revealing the inner chamber structure. The chambers are filled with deep pockets of druzy pyrite crystals.

Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
