The Story Behind the Fossil

Long before humans walked the Earth, ammonites swam through ancient oceans. These marine cephalopods belonged to a group of molluscs related to modern nautiluses, squids, octopuses and cuttlefish. Their coiled shells provided protection and helped support their buoyancy as they moved through the water.

Ammonites were especially successful marine animals, evolving into numerous species with distinctive shell shapes, sizes and patterns. Their fossils are particularly valuable to palaeontologists because different ammonite species lived during specific geological periods, helping scientists determine the relative ages of sedimentary rocks.

Over millions of years, the remains of these animals were buried beneath layers of sediment. Mineralisation and geological processes preserved their shells, creating the fossils that collectors can appreciate today.

This specimen's tightly coiled form and prominent ribbing offer a fascinating glimpse into the anatomy of an ancient marine animal. Its naturally weathered surface also highlights the changes that can occur during fossilisation and preservation.

Madagascar: A Land of Ancient Fossils

Madagascar is internationally recognised for its remarkable fossil deposits and geological diversity. Its sedimentary formations have preserved an extraordinary record of ancient marine life, including ammonites and other marine invertebrates.
