Ammonites appeared during the Carboniferous period a mere 290 to 354 million years

ago. Evolving during the Mesozoic era into specimens sometimes weighing more than 200

lbs., they became very widespread until dying out about the same time as the dinosaurs.

Today the best Ammonites are found on the banks of the Volga River near the Russian city

of Ulyanovsk (formerly Simbirsk and the birthplace of Lenin). These stunning cabochons

are the result of Pyrite replacing the original bone structure of the Ammonite. There are

various shades of brown, beige, black, tan and white. Throughout many of the pieces are

swirls and pockets of Pyrite drusy.
