Fossil tooth fragment

Likely fossilized shark tooth or marine vertebrate tooth; exact taxon cannot be determined from the image

AI-generated identification · may be incorrect

Cream-colored, dense, curved enamel/dentine with a serrated-looking broken edge; fossils commonly have Mohs hardness about 5–6, dull to slightly glossy luster, and no crystal cleavage.

Physical properties

Cream-colored, dense, curved enamel/dentine with a serrated-looking broken edge; fossils commonly have Mohs hardness about 5–6, dull to slightly glossy luster, and no crystal cleavage.

Formation & geological history

A biological tooth was buried in marine sediment and mineralized through diagenesis, typically replacing or infilling organic tissue with silica, calcite, or phosphate over thousands to millions of years.

Uses & applications

Primarily a collecting, educational, and display specimen; value depends on species, completeness, preservation, and provenance rather than industrial use.

Geological facts

The visible ridged margin may represent tooth serrations or internal growth/abrasion features, but its identity is uncertain because the specimen appears partial and possibly worn.

Field identification & locations

Inspect for enamel–dentine contrast, porous broken surfaces, mineral infill, and natural patina; compare with authenticated shark, ray, or reptile teeth. Common sources include marine sedimentary deposits and fossil beds worldwide.
