Fossil - Rare Bearpaw Ammonite

Fossils and RelatedRare Bearpaw Ammonite.

Rare Bearpaw Ammonite from the Bearpaw Formation, Canada.
Beautiful 14.5” Bearpaw Ammonite, Placenticeras Intercalare, from the Black Bearpaw Shales of Southern Alberta, Canada, 110 to 65 million years old. This type of ammonite is highly prized by collectors. They are larger than most species found and have a highly complex fractal suture pattern where the chamber walls expand from a one-dimensional form to become a two-dimensional shell covering. Due to size and physical limitations, they cannot be excavated by mechanized methods, but must be recovered by hand. The mother-of-pearl shell has been transformed into a precious gem called Ammolite. This specimen has been restored, as almost all ammonites of this type have. This is a partial specimen, but still retains a large amount of light reflecting shell. This Bearpaw has a base color of deep red that changes to green and gold as the light angle changes.
