Pyritised Ammonite

Product description

A beautiful Pyritised Ammonite, Perisphinctes kosmoceras, discovered near the Volga River, Ulyanovsk Region, Russia.

It dates from the Jurassic Period, 150 million years old.

These ammonites died in a sea which had a heavy concentration of iron. The iron reactedwith sulphur in the waterto produce iron pyrite, which replaced the ammonite structure.

A wonderful gift idea.

Size:  4.0 cms diameter
