    A SUPERB AMMONITE FROM BAJA
    Pachydiscus catarinae (Neodesmoceras)
    Cretaceous
    Rosario Formation, Baja California Norte, Mexico

    These gorgeous ammonites were first discovered during quarrying operations started in the early 1800's to supply some of the lovely marble and limestone that was used in the post Gold Rush building boom in San Francisco as it developed into an international business and trade center. Classical architecture and high rise buildings lent an aura of sophistication and opulence to what was once a dangerous and dingy port city as the wealth borne of the Gold Rush found its way into monuments to the new wealth and splendor of the city's elite. These quarries were located south of Ensenada, and ships loaded with the building stone would sometimes have a few of these interesting and very rare ammonites sent along with the shipment which then found their way into museums and private collections in the newly affluent California. The quarries that once produced these fabulous specimens have been closed for over 50 years and private collecting is no longer allowed in Mexico making these ammonites irreplaceable. Pachydiscus were especially prized for their large size, very fat or inflated shape, and especially, for the beautiful suture, or growth, lines which form frond-like patterns over their entire surface. This specimen is especially aesthetic with nearly perfect suture lines and a lovely onyx-brown color. Measures 8 ½ x 7 ½ x 4 inches thick at its widest.


    Estimate: $2,000 - $2,500.

    It would indeed have been much simpler to work with a local auction house, and we had local options. But we never once regretted going with Heritage.
