    SPECTACULAR "GEM" AMMONITE IN MATRIX
    Placenticeras costatum
    Late Cretaceous, Bearpaw Formation
    Alberta, Canada

    One look at this stunning "Gem" Ammonite, with its vibrant colors flashing in stark contrast to the deep black shale matrix, and there is no doubt this is a exceptional specimen. As matrix pieces go, this is simply as good as they come. The fossil shell is in superb condition, and it burns with torrid reds and electric greens all the while sitting elegantly on its natural background of black shale. This specimen is not only extremely beautiful, but is exceptional in both sheer size and quality.

    Undoubtedly from the renowned Bearpaw Formation of Southern Alberta, Canada - the premier locality for "gem" Ammonites and the only place on the globe that produces specimens with such vibrant, bold and unbelievable colors - this spectacular Ammonite, over 20 inches in diameter, demonstrates why these pieces are some of the most prized and sought after fossils from any locality worldwide. The colors are a function of the preservation of the shell nacre during fossilization. The stunning coloration is so outstanding that the World Jewelry Confederation accorded this fossilized shell material the status of a gemstone, formally named Ammolite, in 1981. The only significant deposits of gem-quality Ammolite are found in the Bearpaw Formation, and this approximately 70 million year old example of these Canadian National Treasures, has been fitted for wall hanging with double metal cleat hangers to support its significant weight. It comes with a Certificate of Authenticity. This truly "museum quality" fossil is worthy of any home, office, institution or gallery.
    Overall Measurements: 36.25 x 31 inches (92.08 x 78.74 cm)


    Estimate: $60,000 - $75,000.
