Physical properties
Hardness: 3-4 (calcite/aragonite), Color: Off-white to gray, Luster: Vitreous to dull, Crystal structure: Orthorhombic/Hexagonal (mineral dependent)
Formation & geological history
Formed through permineralization or replacement of the original shell material by minerals like calcite, aragonite, or silica over thousands to millions of years in sedimentary environments.
Uses & applications
Used in educational exhibits, fossil collecting, and decorative display items.
Geological facts
Gastropods are one of the most successful classes of mollusks, dating back over 500 million years to the Cambrian period.
Field identification & locations
Identified by the characteristic coiled spiral shell shape. Frequently found in marine and terrestrial sedimentary rock layers worldwide.
