Aesthetic Crystal-filled Sectioned Ammonite From Madagascar. Ammonites are the extinct relatives of living squid and the chambered nautilus. Their fossilized shells are highly valued both for their beauty and scientific value. This large 9" in diameter ammonite, Pachydiscus, was cut in half to show the incredibly beautiful detail of its interior. As the Ammonite grew, it added additional chambers in a spiral pattern with each chamber with an aragonite wall known as a septa. These are clearly visible in this specimen ranging in color from white to gold. All of the chambers are preserved from the smallest inner chamber all the way out to the living chamber. Some of the chambers are filled with white to honey-colored calcite crystals, while other chambers are open revealing the shell structure. The last four chambers, including the living chamber, were filled with mud, which is now a brownish-green colored rock. This 90-100 million year old ammonite was found in Morondave, Madagascar and would be the perfect specimen for a collector desiring a single spectacular ammonite for his fossil collection or for the collector desiring the best quality available.

Estimated Value $400 - 650.
