Predentary

A predentary is an ossification situated on the front of the lower jaw, which extended the dentary (the main lower jaw bone). A predentary bone has evolved independently in two groups of teleost fish, Istiophoridae and Saurodontidae, and two dinosaur groups, ornithischians and ornithuromorph birds.
