Pegomastax was a tiny, parrot-beaked dinosaur that lived in what is now South Africa. It used its strong jaws and sharp front teeth to chomp on tough plants, like a little dinosaur gardener.1

1

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

2

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

3

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

4

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

5

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

6

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

Pegomastax was named by American paleontologist Paul Sereno in 2012, based on a partial skull discovered in the 1966 to 1967 expedition to the Transkei District of Cape Province, South Africa.1

Scientists are still debating whether the large canine teeth of Pegomastax were used for defense, display, or occasional omnivory.1
