Fossil Ammonites - Quenstedtoceras species - Quenstedtoceras sp.
165 Million Years Old
About the piece
These ammonites have been naturally preserved by Iron Pyrite, an iron sulfide, which has partially filled the shells with crystals. They have not been cut, however, and display a beautiful opalescent luster. These fossils are not found in a hard matrix, but have been set on a decorative piece of stone as a base to protect and display them. Ammonites are an extinct group of marine animals similar to the nautilus. Like the nautilus, ammonites had a soft body with tentacles that emerged from a hollow chambered shell utilized in the manner of a submarine's ballast tanks. Ammonites are often identified by their shell ornamentation and the structures of the wall that divide the shell's chambers. Ammonites are named after the Egyptian god Amun, whose attribute (rams' horns) they were thought to resemble, and their fossils have been collected since prehistoric times. Ammonites are among the most common fossils, being plentiful in locations all over the world. They became extinct at the end of the Cretaceous period, the same time that the dinosaurs disappeared.
