Fossil sea-snail shell

Marine gastropod shell, composed mainly of calcium carbonate (aragonite and/or calcite); species cannot be determined from the image.

AI-generated identification · may be incorrect

Cream to tan, ridged and spiraled shell with a hard, nonmetallic luster. Shell minerals are about Mohs 3–4; the original crystal structure may be altered during fossilization.

Physical properties

Cream to tan, ridged and spiraled shell with a hard, nonmetallic luster. Shell minerals are about Mohs 3–4; the original crystal structure may be altered during fossilization.

Formation & geological history

Formed by a marine gastropod; shells can be buried in seafloor sediment and preserved or mineralized over geological time. The specimen’s age and locality are not identifiable from the image.

Uses & applications

Primarily collected or displayed as a natural-history specimen; fossil shells also help interpret ancient marine environments.

Geological facts

Gastropod fossils are common in marine sedimentary rocks, and shell shape can reveal growth patterns and habitat.

Field identification & locations

The coiled form and raised whorls indicate a gastropod rather than a mineral crystal. No diagnostic details establish whether this is fossilized or a modern shell.
