Iridescent Canadian Ammonite (Ammolite) in Matrix, 16" Specimen
This incredible specimen is a stunning example of an iridescent Canadian ammonite in shale matrix. Its entire shell is preserved with gorgeous ammolite. This unique piece is more three dimensional than most specimens from this locality (no flattening).
Ammolite is a rare, opal-like gemstone found in Alberta's Upper Cretaceous Bearpaw formation, just east of the Rocky Mountains. This piece displays extremely bright hues and all colours of the visible spectrum can be seen. It has excellent overall shape and fine details of the shell structure are present, including the ribbing of the living chamber. Complete specimens, especially with such intense coloration and lustre, are exceedingly rare.
Ammonite measures 41cm (16"), size of the matrix: 80 cm x 64 cm (31.5" x 25")
Deposit: Bearpaw Formation
Location: Southern Alberta, Canada
Age: Late Cretaceous (71 million years old)
Specimen located in Germany.
We offer a variety of Canadian ammonites, including smaller specimens and complete, double-sided specimens outside of the shale matrix (see last photo). We can show you different options in stock over email or arrange a visit at the showroom in Canada.

Ammonites belong to the Mollusca Phylum in a Class known as Cephalopods – “head-footed” creatures such as octopus and squid. They swam in ancient oceans from 400 million years ago, to their extinction, along with the dinosaurs, 65 million years ago.
Ammonites were free floating invertebrates that were attacked by plesiosaurs and mosasaurs, two groups of gigantic marine reptiles. One way that ammonites could avoid an attack was to quickly change their buoyancy levels, zig zagging and sinking rapidly.
These incredible prehistoric animals ranged in size from tiny species only a few centimetres in diameter to the monstrous Cretaceous ammonite, Parapuzosia seppenradensis, which grew to about 3 meters and would probably weigh close to 1500 kilograms!
