Large Opalescent Ammonite on Stand
Bearpaw Formation, Southern Alberta, Canada
Prepared free of matrix, this brilliant ammonite specimen displays a portion of rarely seen blue coloration, adding to the vivid reds, rust-oranges and greens, which are more characteristic in the highly covetable specimens from the famous Bearpaw Formation. The beauty of this example belies its fierce predatory habit as a living squid-like creature which flourished during the Age of Dinosaurs. Desired by collectors the world over, the stunning palette of these marvelous 71 million-year-old ammonites is produced by light interference by the shell layers. This colorful material, known as ammolite, represents one of only two fossils which are also classified as gemstones. In the present specimen, resplendent color is seen on both sides. Offered on a custom oak display stand.
