Physical properties
Hardness: 3-4 on Mohs scale (calcite/aragonite), Color: Off-white to light brown, Luster: Vitreous to dull, Structure: Bivalve shell with prominent radial ribs
Formation & geological history
Formed through the accumulation and fossilization of marine mollusk shells in shallow marine sedimentary environments over millions of years.
Uses & applications
Used in educational displays, fossil collecting, jewelry making, and paleo-environmental studies.
Geological facts
Fossilized shells help scientists reconstruct ancient shorelines, water temperatures, and prehistoric marine ecosystems.
Field identification & locations
Found globally in sedimentary rock layers, particularly limestone and shale formations deposited by ancient shallow seas.
