Physical properties

Hardness varies around 3-4 on Mohs scale depending on mineralization, usually calcium carbonate or silica replacement, spiral shell structure with textured nodular surface.

Formation & geological history

Formed through the process of permineralization or fossilization, where ancient marine organism shells are buried in sediment and preserved over millions of years.

Uses & applications

Valued by fossil collectors, used for educational purposes, and sometimes crafted into decorative items or jewelry.

Geological facts

Fossilized shells provide crucial evidence of ancient marine environments, past climates, and evolutionary history spanning hundreds of millions of years.

Field identification & locations

Found globally in sedimentary rock formations, particularly in ancient marine deposits, limestone beds, and coastal cliffs. Identify by spiral morphology and stony preservation.
