Denticle (tooth feature)
Serrations on teeth
From Wikipedia, the free encyclopedia
Denticles, also called serrations, are small bumps on a tooth that give the tooth a serrated edge. In paleontology, denticle characteristics such as size and density (denticles per unit distance) describe and classify fossilized teeth, especially those of dinosaurs. Denticles are also present on the teeth of varanoid lizards, sharks, and mammals.[1] The term is also used to describe the analogous radular teeth of mollusks.[2][3][4]
