3.3" Cut & Polished, Pyritized Ammonite Fossil - Russia

This is a pyritized ammonite (Quenstedticeras sp.) fossil that was collected from a Middle Jurassic deposit along the banks of the Volga River near Saratov, Russia. It has been cut in half and polished across the flat faces, revealing the pyrite encrusted chambers. You can feel the heft of the iron pyrite in the specimen when you hold it in your hand.

Comes with an acrylic display stand for each half. Larger ammonites from this location will commonly be disarticulated or poorly preserved at their centers. For this reason, there is some gap fill restoration at the center.

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. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
