Physical properties

Hardness 3 to 4 on the Mohs scale, typically gray, brown, or beige, with a dull to vitreous luster and a coiled spiral shell structure.

Formation & geological history

Formed through permineralization or replacement of ancient snail shells by minerals like calcite or silica in marine or freshwater sediments over millions of years.

Uses & applications

Valued by fossil collectors, used in educational displays, and studied for paleoenvironmental reconstruction.

Geological facts

Gastropods are one of the most successful and diverse animal groups, with fossil records dating back over 500 million years to the Cambrian period.

Field identification & locations

Identified by its distinct coiled, spiral morphology and commonly found in limestone and shale deposits worldwide.
