History of Ammonite Fossil Pendant

Ammonites were predatory mollusks that lived in the seas between 240 and 65 million years ago. They went extinct at the same time as the dinosaurs. Their shells were divided into chambers that helped them control buoyancy. Today, they are prized for their Fibonacci-like spiral and are often mineralized with calcite or pyrite, turning into beautiful geological artifacts.
