Heterodontosaurus is a genus of heterodontosaurid dinosaur that lived during the Early Jurassic, 200–190 million years ago. Its only known member species, Heterodontosaurus tucki, was named in 1962 based on a skull discovered in South Africa. The genus name means "different toothed lizard", in reference to its unusual, heterodont dentition; the specific name honours G. C. Tuck, who supported the discoverers. Further specimens have since been found, including an almost complete skeleton in 1966. Though it was a small dinosaur, Heterodontosaurus was one of the largest members of its family, reaching between 1.18 m (3 ft 10 in) and possibly 1.75 m (5 ft 9 in) in length, and weighing between 2…

Geranosaurus is a genus of heterodontosaurid ornithischian dinosaur that lived during the Early Jurassic, between 191.1 and 187.5 million years ago. It is known from a single species, G. atavus, that was named in 1911 by Robert Broom for partial jaws found during road-cutting in South Africa. The genus name is likely derived from the word for "crane" in reference to the bird-like limb bones, while the species name means "ancestor" likely in reference to its position as an early ornithischian. The limited material and poor preservation of Geranosaurus have rendered it difficult to diagnose, with authors accepting it as a dubious name though differentiable from its relative Heterodontosaurus,…

Pegomastax is a genus of heterodontosaurid dinosaur that lived during the Early Jurassic of South Africa. The only known specimen was discovered in a 1966–1967 expedition in Transkei District of Cape Province, but was not described until 2012 when Paul Sereno named it as the new taxon Pegomastax africana. The genus name is derived from the Greek for "strong jaw", and the species name describes the provenance of Africa; it was originally spelled africanus, was corrected to africana to align with the gender of the genus name. The only known material of Pegomastax included a partial skull with well-preserved lower jaw and teeth, showing affinities for Heterodontosaurus and the group with a dee…

Lesothosaurus is a monospecific genus of ornithischian dinosaur that lived during the Early Jurassic in what is now South Africa and Lesotho. It was named by paleontologist Peter Galton in 1978, the name meaning "lizard from Lesotho". The genus has only one valid species, Lesothosaurus diagnosticus. Lesothosaurus is one of the most completely-known early ornithischians, based on numerous skull and postcranial fossils from the Upper Elliot Formation. It had a simpler tooth and jaw anatomy than later ornithischians, and may have been omnivorous in some parts of the year.
