Nautilus Fossil with Crystalline Infill – Albian (Cretaceous) – 100% Natural An impressive fossil nautilus from the Albian stage of the Cretaceous period, approximately 110 million years old. This specimen preserves the characteristic coiled shell form with fine external details visible, enhanced by shades of ochre, red, and earthy tones. A particularly striking feature is the partially open chamber, where natural mineralization has produced a sparkling crystalline infill. This adds both scientific interest and aesthetic appeal, offering a glimpse into the unique fossilization processes that took place over millions of years. Entirely natural and free of restoration, this specimen is both geologically and visually remarkable. It represents a rare opportunity to acquire a nautilus fossil that combines authenticity with strong display value.
