Ankylosaurus tooth with large denticles

Denticles or serrations are small bumps on a tooth that give the tooth a cutting edge.

In paleontology, denticle features are used to describe and classify fossilized teeth, especially those of dinosaurs.

Denticles are also present on the teeth of some lizards, sharks, and mammals.
