Trio Of Pyritized Russian Ammonites. Some of the most beautiful ammonites come from a small 160 Million year old section of the Volga River in the Ulianosk area of Russia. These Kosmoceras species ammonites are so highly value because of the beauty of their fossilization. When the ammonite is cut in half, the entire ammonite has been replaced with pyrite including many of the chambers that are filled with glittering crystals of pyrite also know as fools gold. This fossil consists of a three 1.50-1.75 inch diameter complete ammonites that have been cut in half revealing their open inner chambers filled with pyrite. Pyrite preservation in ammonites is very rare as most ammonites are preserved as fossils with calcite. Only in this small section of the Volga River were conditions just right for this beautiful pyrite preservation. In addition smaller complete ammonites have been placed in the center of each polished half for esthetic display. The ammonites have been placed back onto the hard black slate matrix with a cream colored interior similar to the matrix they were removed from making for a beautiful display.
