Physical properties

Hardness varies by mineral replacement (typically Mohs 3-4 for calcite), brownish-red color, dull to vitreous luster, spiral univalve shell structure.

Formation & geological history

Formed through perimineralization and sediment replacement in ancient aquatic environments, often dating from the Paleozoic to Cenozoic eras.

Uses & applications

Valued as a collector specimen, educational tool, and for relative dating of sedimentary strata.

Geological facts

Gastropods are one of the most successful animal classes, with a fossil record spanning over 500 million years.

Field identification & locations

Identified by the distinct coiled spiral morphology; commonly found in limestone and shale deposits worldwide.
