DiscoveryPegomastax was found in Voyizane, Joe Gqabi District, Cape Province, in rocks of the upper Elliot Formation, a rock formation that dates to the early part of the Early Jurassic. It was collected during a 1966–1967 expedition but not officially named until 2012, when Paul Sereno published a description on this strange little dinosaur. The type species is Pegomastax africanas.
Pegomastax differed from other heterodontosaurids by its skull. The lower jaw was robust with a short beak. Like most other heterodontosaurids, Pegomastax had an enlarged canine-like tooth at the beginning of the lower jaw's tooth row, which may have had a defensive function or a digging tool for finding roots and shrubs that it likely ate. Another way it differs from other heterodontosaurs is that it had almost porcupine-like spikes coming all throughout its body. This could either be used as a defensive function, like porcupines, to make it look unappealing to eat for predators, or to make itself look bigger to intimidate rivals or predators and attract mates. This little heterodontosaurs was one of the smallest dinosaurs, growing only 60 cm (2 feet) from head to tail. It was likely bipedal, and like its relatives, was probably a fast runner.
