Description

For sale is a beautifully preserved Cleoniceras grycia besaivei fossil ammonite, displaying stunning natural mother of pearl iridescence. This exceptional specimen is from the Lower Albian stage of the Early Cretaceous Period, approximately 113 to 100 million years ago, and was discovered in Mitsinjo, Madagascar, a location celebrated for yielding some of the world’s most vividly preserved ammonite fossils.

Cleoniceras is a genus of smooth, fast-moving, open-water ammonites, easily distinguished by their streamlined, coiled shells. They were highly successful marine cephalopods, swimming the warm Cretaceous seas. The natural aragonite layers of their shells have fossilised in some cases into breathtaking displays of iridescence, like the specimen offered here.

This piece features striking flashes of natural rainbow colours across the shell, making it a highly desirable addition to any fossil collection, educational display, or even as a unique natural art piece.
