Physical properties

Hardness: 5 (Mohs scale), Color: tan to light brown, Luster: vitreous (enamel), triangular shape, lacking serrations on the edges, visible root structure.

Formation & geological history

Formed via permineralization where organic tooth material is replaced by minerals (calcium phosphate) in marine sediments. This specimen likely dates to the Late Paleocene to Early Eocene epochs, roughly 50-60 million years ago.

Uses & applications

Scientific research, educational displays, jewelry, and private fossil collecting.

Geological facts

Otodus is an extinct genus of mackerel shark that was the ancestor to the famous Megalodon. Teeth like this are often found in the phosphate mines of Morocco.

Field identification & locations

Identify by its triangular crown and generally thick, robust root. Often found in riverbeds or coastal cliffs with exposed ancient seabed strata. Look for the distinct glossy enamel covering the blade.
