LARGE PAIR OF PYRITIZED AMMONITE SLICES
Spiticeras sp.
Jurassic
Volga River, Ulianovsk Area, Russia
In one small area along the Volga River, ancient Jurassic Ammonites are found with their entire shell been turned to shimmering, silvery Pyrite. Specimens are sliced and the inner surfaces brought to a high polish to emphasize their incredible natural beauty. The living chambers present a dramatic contrast in metallic black, clearly demarcated by waving, silvery lines of pyrite, whilst the inner chambers have been preserved as fantastic, druzy vugs, shimmering with Pyrite crystals. Three are further filled with lovely warm honey-brown Calcite, and the sliced halves together make for a superb display pair, each 17¼ inches in diameter.
