Ammonite

Category Properties:

Ammonite is an extinct group of prehistoric squidlike creatures that lived inside coil-shaped shells. Ammonite fossils, such as many found in Madagascar and Alberta (Canada), display iridescence. These iridescent ammonites are often of gem quality (ammolite) when polished. In no case would this iridescence have been visible during the animal's life; additional shell layers covered it.

Ammonite fossils became less abundant during the latter part of the Mesozoic, with none surviving into the Cenozoic era. The last surviving lines disappeared along with the dinosaurs 65 million years ago in the Cretaceous-Tertiary extinction event. These are amazing natural fossilized shell specimens.
