The Pygurus marmonti fossil sand dollar sea urchin offers a direct connection to Jurassic oceans that existed nearly 200 million years ago. Its beautifully preserved five-pointed star pattern reveals the natural symmetry of this ancient echinoid, making each specimen both scientifically fascinating and visually striking. Fossils from Madagascar are especially admired for their natural polish and balanced form.

These sea urchins once burrowed quietly beneath shallow ocean sediments. After death, their protective shells became buried and slowly transformed into stone through mineralization, preserving their delicate patterns for millions of years. Today, Pygurus marmonti fossils stand as lasting reminders of prehistoric marine life and the artistry of natural fossil formation.

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.
