Ammonite fossils are the spiralized remnants of ancient marine creatures related to modern-day squids and octopuses. These extinct mollusks had coiled shells that grew in a logarithmic spiral, and over millions of years, their shells became mineralized, preserving intricate patterns. Ammonites lived during the Mesozoic era, and their fossilized shells are now treasured for their unique, almost otherworldly appearance, offering a glimpse into prehistoric oceans.
