Description
Offered here is a stunning Cleoniceras fossil ammonite, known for its vivid iridescent mother of pearl shell, originating from the Lower Albian stage of the Early Cretaceous period (approximately 113 to 100 million years ago). This exceptional specimen was discovered in Madagascar, a world-famous location for fossil ammonites of outstanding preservation and beauty.
Cleoniceras is an extinct genus of ammonite cephalopods, distinguished by their finely ribbed and coiled shells. During the Cretaceous period, these marine animals thrived in warm shallow seas, and their fossilised shells today often preserve an extraordinary rainbow-like iridescence caused by layers of fossilised aragonite.
This specimen has been carefully polished to reveal the inner beauty of the fossil, displaying an array of shimmering colours, from deep greens and blues to flashes of pink, gold, and violet. Such vivid nacreous preservation makes this Cleoniceras a highly desirable fossil for collectors, educators, and natural history enthusiasts.
