Ammolite comes from the fossil shells of the Upper Cretaceous disk-shaped ammonites Placenticeras meeki and Placenticeras intercalare, and Baculites compressus. Ammonites were squid-like creatures that thrived in tropical seas until becoming extinct along with the dinosaurs at the end of the Mesozoic era.The ammonites that form ammolite inhabited a prehistoric, inland subtropical sea that bordered the Rocky Mountains. As the seas receded, the ammonites were buried by layers of bentonite sediment. This sediment preserved the aragonite of their shelled remains, preventing it from converting to calcite.
The Kainah Nation is a First Nation in southern Alberta, Canada with a population of just under 10,000 members. Their name translates to "Many Chief people." The common English name for the tribe is the "Blood Tribe." For thousands of years they have called the area along the Oldman, Belly, and St. Mary rivers west of Lethbridge, Alberta their home, with ammolite being an integral part of their culture.
