1.5" Cut Pyritized Ammonite (Pleuroceras) Fossil Pair - Germany

This is a gorgeous pyritized/agatized ammonite (Pleuroceras spinatum) fossil collected from the Holzbachacker clay pit of Buttenheim, Bavaria/Germany. It's Jurassic, Pliensbachian stage or approximately 190 million years old. It has been cut and polished, allowing for the gorgeous mineralizations within and around the chambers of the ammonite to be seen. You can feel the heft of the iron pyrite in the specimen when you hold it in your hand.

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.
