    Description

    "Gem" Ammonite Fossil
    Placenticeras sp.
    Cretaceous
    Bearpaw Formation
    Southern Alberta, Canada

    The famous Bearpaw Formation produces incredible gemmy Ammonites that are known for vivid colors and the unusual preservation resulting in Ammolite, which is both a fossil and a gemstone. This colorful example reflects electric green and intense red hues on both sides of this ancient shell. This Ammonite exhibits a nicely inflated form and good balance over the entire shell, which is a phenomenal aspect, as most fossils from this renowned locality tend to evidence considerable compression. The coverage of color over the surface is nearly complete, and one side features some small sediment filled round holes, which could represent Mosasaur bite marks as they were known to have preyed on shelled cephalopods. The small fossil exudes vibrant color and decorative appeal.
    Overall Measurements: 4.56 x 3.87 x 1.19 inches (11.59 x 9.82 x 3.03 cm)

    [Scale: 1 inch, with mark at 1 cm]


    Estimate: $8,000 - $12,000.
