Dinosaurs Inside and Out

Teeth and Claws

What bones held the dinosaur’s teeth?

Dinosaurs had two bones in the upper jaw that held teeth. The larger bone holding the majority of the upper teeth were located toward the back of the snout (called the maxilla). The smaller bone holding fewer teeth (called the premaxilla) was located at the front of the skull. Teeth were held by the dentary section of the lower jaw; these teeth are called dentary teeth.
