Silver/grey ammonite fossil – iridescent whole specimen from madagascar – cretaceous period – natural marine cephalopod – coa

Description This listing features a beautiful Silver/Grey Whole Ammonite Fossil from Madagascar, dating to the Cretaceous Period, approximately 145 to 66 million years ago. Ammonites are among the most instantly recognisable of all fossils, known for their distinctive spiral-shaped shells which bear a striking resemblance to modern snail shells—although they are, in fact, unrelated. Ammonites were marine molluscs with coiled external shells. Although they looked similar to today’s nautilus, they are more closely related to the modern squid, octopus, and cuttlefish—collectively known as coleoids. These ancient creatures lived in the world’s oceans for millions of years, and their fossils have been discovered on every continent. This particular specimen is notable for its gorgeous silver/grey coloration and pearlescent iridescent sheen, which catches the light beautifully. Madagascan ammonites are celebrated for their exceptional preservation and natural beauty, often found in limestone matrices which enhance their stunning detail. This whole fossil ammonite is a fascinating piece of natural history, ideal for fossil collectors, geology enthusiasts, or those looking for a unique and scientifically significant decorative piece.
