Douvilleiceras is an extinct genus of ammonite from the Cretaceous Period, commonly associated with marine deposits that date back roughly 100 million years. Ammonites were ancient shelled cephalopods related to modern squid, octopus, and nautilus. Madagascar is one of the world’s best-known sources for ammonite fossils, producing many highly collectible specimens with excellent preservation, strong ribbing, and decorative natural patterns.

Spiritually, ammonites are often associated with transformation, grounding, ancient wisdom, and life cycles. Their spiral form is commonly seen as a symbol of growth, evolution, protection, and the natural flow of time. Many collectors enjoy ammonites not only as fossils, but also as meaningful display pieces connected to Earth history and personal transformation.
