Physical properties
Hardness: 3-4 (Calcite/Aragonite), Color: Brown and white, Luster: Pearly to dull, Composition: Calcium carbonate, Structure: Spiral/Conical shell shape.
Formation & geological history
Formed through the process of permineralization or replacement where biological shell material is preserved or replaced by minerals in marine sedimentary environments over thousands to millions of years.
Uses & applications
Primarily used for educational purposes, scientific study, jewelry (when polished), and as collector's items.
Geological facts
Gastropods are one of the most successful lineages of mollusks, dating back over 500 million years to the Cambrian period. This specimen shows a distinct spiral growth pattern common to sea snails.
Field identification & locations
Identified by its conical spiral shape and evidence of nacre (mother of pearl). Commonly found in limestone outcrops, coastal sedimentary deposits, or ancient seabed formations.
