Description

For sale is a beautiful Desmoceras medium fossil ammonite, featuring incredible natural iridescence preserved from its original mother of pearl shell. This fossil dates back to the Lower Albian stage of the Early Cretaceous Period, approximately 113 to 100 million years ago, and was discovered in Maritano, Madagascar, a region famous for its exquisitely preserved ammonites.

Desmoceras is a genus of smooth, rounded ammonites known for their relatively simple shell ornamentation and superb preservation quality. During the Early Cretaceous, these cephalopods thrived in the shallow tropical seas that covered much of what is now Madagascar. Their shells, originally made of aragonite, occasionally fossilised with a stunning nacreous layer, giving rise to the gorgeous iridescent effect we see today.
