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, a composite ammonite has been placed at the center. There is also some damage along one edge, this has been reflected in the price.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
