Denticles, also called serrations, are small bumps on a tooth that serve to give the tooth a serrated edge. In paleontology, denticle characteristics such as size and density (denticles per unit distance) are used to describe and classify fossilized teeth, especially those of dinosaurs. Denticles are also present on the teeth of varanoid lizards, sharks, and mammals.
A denticle is any small tooth-like or bristle-like structure. "Denticle" may refer to:
Denticle (tooth feature), serrations on the teeth of dinosaurs, lizards, sharks, and mammals
Dermal denticles or placoid scales, in cartilaginous fishes
Pulp stone or endolith, a calcified mass in the pulp of a tooth
