This is a beautiful ammonite fossil. It is a very fine specimen of Hoploscaphites nebrascensis from the Cretaceous of South Dakota. This type of ammonite has distinct ribbing and a somewhat squared keel. There is one rows of prominent nodes on the shoulders and near the keel of the ammonite. These features are very clearly defined on this specimen. But the most striking feature of this ammonite is its natural color. The dark, iridescent shell of this ammonite is very easily seen. It is almost opalescent in nature - very shiny. This is an unusual type of iridescent ammonite from the Black Hills.
