Precious Ammolite Ammonite from Bearpaw

Description: A spectacular ammonite know as Placenticeras meeki from Canada which has been polished to show the wonderful fire opal iridescence for which they are known. This is a consequence of light passing through the various layers of aragonite and conchiolin deposited by the ammonite in life. The lack of acidity in the depositional environment allowed them to be preserved as you see it here. Jewel-quality material such as this coming from Alberta, Canada is termed “Ammolite” in the trade, and typically commands a high price. I was able to secure a very few less expensive examples at the 2017 Tucson Fossil Show, and will be offering them on a first come, first served basis. The specimen comes with a certificate of authenticity from the source.
