The Pygurus marmonti fossil sand dollar is a remarkable example of Jurassic marine life preserved in stone. Dating from approximately 145–200 million years ago, this fossil sea urchin features a prominent five-pointed star design, created by its complex internal structure. Specimens from Madagascar often display exceptional symmetry and natural polish that highlight their intricate details.

These echinoids once lived in shallow coastal waters, burrowing into soft ocean floors. Over millions of years, their durable shells were buried under sediment and transformed through mineralization processes, preserving their form as detailed fossils. Today, Pygurus marmonti fossils are admired for both their geological significance and decorative beauty.

Please be aware of the nature of fossils:

Being buried under the ground for millions of years under tons of pressure tends to be rough. No fossil comes out of the ground whole and perfect. Most fossils have undergone some restoration, while others are altered by man simply to enhance their presentation in different ways. The workers in Madagascar do a very professional job of unearthing and preserving these natural treasures; however, natural cracks are visible on the surface. These are part of the natural beauty of the fossil and are not considered defects.
