Ammolite fossils are rare and exquisite gemstones formed from the fossilized shells of ancient marine mollusks known as ammonites. These iridescent gems are treasured for their vibrant play-of-color, which rivals that of opals and other precious stones.

Ammolite originates from the shells of extinct ammonites that inhabited oceans millions of years ago, primarily during the Late Cretaceous period. Over time, the aragonite shells of these mollusks underwent a process of fossilization and mineralization, resulting in the formation of ammolite.

What sets ammolite apart is its stunning display of colors, which shimmer and shift with changes in lighting and viewing angles. These colors, ranging from vivid greens and blues to fiery reds and oranges, are created by the interference of light as it passes through the layers of microcrystalline aragonite within the fossilized shell.

Ammolite is found primarily in the Bearpaw Formation in Alberta, Canada, where it is carefully extracted from fossilized ammonite shells. Due to its rarity and unique beauty, ammolite is highly prized by collectors, jewelry designers, and enthusiasts alike, serving as a symbol of Earth’s ancient history and natural splendor.

Canadian ammolite fossils are among the most unique and vibrant fossils available, known for their stunning iridescent colors that reflect a beautiful range of reds, greens, and golds. Originating from the Canadian provinces of Alberta and Saskatchewan, these fossils are the result of the ancient ammonite shells being fossilized in a way that preserves their vibrant, opal-like sheen. Canadian ammolite is highly prized for its natural beauty and rarity, making it a favorite among collectors, jewelers, and fossil enthusiasts. The iridescent properties of ammolite make it stand out among other fossils, offering an extraordinary display of nature’s artistry.

Ammolite fossils from Canada are available in various sizes and price ranges, with affordable pieces starting at just a few dollars for smaller specimens. The prices for these genuine fossils can vary significantly based on their size, quality, and color intensity, with larger, more vibrant pieces commanding higher prices. Canadian ammolite fossils not only provide a fascinating glimpse into the ancient marine life of the Cretaceous period but also make beautiful, one-of-a-kind additions to any collection. With their unique iridescence and geological significance, Canadian ammolite fossils offer a perfect opportunity to own a rare and beautiful piece of Earth’s history.

Ammolites in Alberta, Canada

1. What is an ammonite?
In Alberta, the term ammolite refers to a rare and colorful gemstone formed from the fossilized shells of ammonites. These ancient marine creatures once lived in the region during the Cretaceous period, around 70 to 75 million years ago. Ammonites are cephalopods, related to modern squid, octopuses, and nautilus. Unlike their relatives, ammonites had hard, spiral-shaped shells that were made of aragonite. Over millions of years, the shells of ammonites in certain parts of Alberta underwent a process of mineralization, turning into vibrant gemstones known as ammolite, which are valued for their beautiful play of color.

2. How old are Alberta ammolites?
The ammolites found in Alberta date back to the Cretaceous period, approximately 70 to 75 million years ago. This time frame corresponds to when ammonites, the creatures that created these shells, thrived in shallow seas that once covered much of western North America. Over millions of years, the shells of these ammonites were buried by sediment, and under the right conditions of pressure and mineralization, they transformed into the iridescent gemstones we now call ammolites.

3. Where are ammolites found in Alberta?
Ammolites are primarily found in the Badlands of southern Alberta, particularly around the areas near the town of Lethbridge. The fossil-rich deposits are located in the rocks of the Bearpaw Formation, which was once part of a vast inland sea. This region is known for its unique geology and rich fossil deposits, and it is one of the few places in the world where ammolites are found. The Alberta Badlands, with their exposed rock layers, have become a prime location for fossil hunters seeking these precious ammonite remains.

4. How many species of ammonites are there in Alberta?
In Alberta, there are many species of ammonites that contributed to the formation of ammolite, though the exact number is difficult to determine. It is estimated that around 70 species of ammonites were present in the region during the Cretaceous period. Among them, species from the genus Placenticeras are particularly notable for producing the vibrant ammolite gemstones. These species are characterized by their large, spiral shells, which often preserve well enough to form ammolite. The diversity of ammonites in the area provides a range of colors and patterns in the ammolite gemstones found today.

5. How big did ammonites get in Alberta?
Ammonites in Alberta, particularly those from the genus Placenticeras, could grow quite large. Some of these ammonites reached impressive sizes, with their shells growing up to 1 meter (3.3 feet) in diameter. These giant ammonites had broad, coiled shells that were capable of producing large, well-preserved fossilized material that could later be transformed into ammolite gemstones. While most ammolites are found in smaller pieces, the larger ammonites contributed to some of the more spectacular examples of ammolite, showcasing intricate patterns and vibrant colors.
