Ammonite Fossil 11 1/2 inches #17580

Up for sale is a nice ammonite fossil. This particular ammonite is from a very old collection that has been in storage since the 1970s. I think these ammonites are pretty rare but I don’t know the location where it was found. This ammonite has had some sort of clear coat or protection applied to the back side of the ammonite but the front, polished side is clear and has beautiful crystalline chambers. Ammonites were soft-bodied marine molluscs that lived in a spiral, compressed, multi-chambered shells. The outermost chamber of the shell housed the animal itself. The earliest ammonites appeared during the Devonian time period, about 400 million years ago, and the last ammonites vanished in the Cretaceous time period, approximately 66 million years ago, as a result of the K-T event, that killed the Dinosaurs.
