Fossilized tooth, likely mammalian molar

Indeterminate Mammalia; mineralized dentine and enamel

AI-generated identification · may be incorrect

Rounded, off-white specimen with a dark exposed cavity and possible enamel/dentine layering; apparent hardness roughly 4–6 Mohs, but exact properties cannot be confirmed from the image. The shape and surface texture suggest a fossil tooth rather than a mineral or ordinary rock.

Physical properties

Rounded, off-white specimen with a dark exposed cavity and possible enamel/dentine layering; apparent hardness roughly 4–6 Mohs, but exact properties cannot be confirmed from the image. The shape and surface texture suggest a fossil tooth rather than a mineral or ordinary rock.

Formation & geological history

Formed biologically, then buried and permineralized as groundwater replaced or filled dentine pores with silica, calcite, or iron minerals. Geological age and species cannot be determined without scale, locality, and examination of the crown and roots.

Uses & applications

Primarily a natural-history or educational collectible; not generally used in industry, construction, or jewelry. Scientific value depends on secure locality and taxonomic identification.

Geological facts

The dark area may be a broken root or internal pulp cavity, while the pale outer material may be enamel or mineralized dentine. Similar objects can also be modern teeth or bone, so fossil status is provisional.

Field identification & locations

Check for clearly preserved enamel, dentine tubules, root structure, and mineral infill; compare weight and texture with modern tooth material. Estimated value: $5–$50 if common and unidentified, potentially $100–$500+ with verified species and provenance.
