Pegomastax had a very deep, parrot-like beak at the front of its jaw, which helped it bite into tough plants.1

Its skull was only about 73 mm (2.9 inches) long, smaller than a chicken's skull.1

Pegomastax lived alongside many other dinosaurs, including the long-necked Massospondylus and the small ornithischian Lesothosaurus.1

The only fossil of Pegomastax is a partial skull with a well-preserved lower jaw and teeth, found in the upper Elliot Formation.1

Scientists think Pegomastax may have been most closely related to a South American dinosaur called Manidens.1

Pegomastax had a mobile predentary bone in its lower jaw, which helped it move its beak up and down while chewing.1
