Description
This listing features a stunning silver/grey whole ammonite fossil, dating to the Cretaceous period, approximately 100 to 145 million years ago, and found in the fossil-rich layers of Madagascar. These fossils represent an extinct group of marine molluscs that once dominated the world’s oceans for over 175 million years.
Ammonites are best known for their distinctive spiral-shaped shells, making them one of the most recognisable and sought-after fossils globally. Despite their outward resemblance to snails, ammonites were cephalopods, more closely related to modern squid, octopuses, and cuttlefish. Their coiled shells consisted of a series of internal chambers used to regulate buoyancy, allowing them to move efficiently through prehistoric seas.
This particular specimen displays a natural pearlescent shimmer, a feature that results from the fossilisation process and mineral content of the shell. The outer surface reflects light in silver, grey, and sometimes subtle rainbow tones, making it especially attractive as a display piece or collector’s item.
Geological Context: Sourced from Madagascar, a country famed for its exceptional fossil preservation, this ammonite was formed in shallow tropical marine sediments during the Cretaceous. These seas were home to diverse marine life, and Madagascar’s fossil beds preserve ammonites in superb detail and condition.
