Trityldon


Trityldon (Greek for 3 cusped tooth) was a species of tritylodont, one of the most advanced group of cynodont therapsids. They lived in the Early Jurassic and possibly Late Triassic periods along with dinosaurs. They also shared a lot of characteristics with mammals, and were once considered mammals because of overall skeleton construction. That was changed due to them retaining the vestigial reptilian jawbones and a different skull structure. Trityldons are now regarded as synapsids (often called "mammal-like reptiles").
