The story of the word

Richard Owen named the Cynodontia in 1861 for what their jaws were doing. Reptile teeth are a row of near-identical pegs; in these animals the row broke up into incisors, canines and cheek teeth that met and sheared, which is the mammal pattern. The canine is the dog tooth in English too, and in Greek κυνόδους meant exactly that.
