1.3" Iridescent Ammonite (Quenstedtoceras) Fossil in Rock - Poland

 
This is an absolutely gorgeous, Quenstedtoceras ammonite fossil in rock from Poland. These ammonites are Jurassic in age, or approximately 178 million years old. You can feel the weight during the internal pyritization of the fossil, and the shell has a beautiful iridescence to it. There are additional partial pyritized ammonites scattered throughout the rock.



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.
