Physical properties
Hardness: 3-4 (Mohs scale), Color: Creamy white with brown accents, Luster: Dull/Matte, Structure: Spiral whorls with spiked or fluted varices, Specific gravity: 2.7
Formation & geological history
Formed through permineralization or replacement of shell materials by minerals (usually calcite) in marine sedimentary environments during the Cenozoic era.
Uses & applications
Decorative display, educational use in paleontology, and personal collections.
Geological facts
Murex shells have been prized since antiquity; the Phoenicians used certain species to produce 'Tyrian Purple' dye. As fossils, they provide evidence of ancient sea levels and temperatures.
Field identification & locations
Identified by its distinctive spiral shape and rows of spines or ridges. Commonly found in limestone or marl deposits in coastal regions such as Florida, the Caribbean, or Western Europe.
