Surangular Explained

The surangular or suprangular is a jaw bone found in most land vertebrates, except mammals. Usually in the back of the jaw, on the upper edge,[1] it is connected to all other jaw bones: dentary, angular, splenial and articular. It is often a muscle attachment site. It has been noted in dinosaurs.[2]
