This exquisite Agatised Gastropod fossil comes from the Devonian period, approximately 400 million years ago, and was discovered in Madagascar. Gastropods, commonly known as snails, were abundant in ancient marine environments, and this fossil beautifully captures the early evolutionary stages of these fascinating creatures.

What sets this fossil apart is that it has undergone a process called agatization, where the original organic material has been replaced by the mineral agate over millions of years. Agatization is a rare and captivating natural process, which occurs when groundwater rich in silica flows through sediment. Over time, the silica gradually replaces the organic material with agate, preserving intricate details of the gastropod while adding vibrant colors and patterns, giving the fossil a gem-like appearance.
