Heterodontosaurus was a dinosaur of the Early Jurassic, 200–190 million years ago. It was named in 1962 after a skull fossil was discovered in South Africa. The genus name means "different toothed lizard", in reference to its unusual heterodont dentition, including small, incisor-like teeth in the upper jaw, followed by long, canine-like tusks. Additional specimens have 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 and possibly 1.75 m in length, and weighing between 2 and 10 kg. The body was short with a long tail. The five-fingered forelimbs were long and relatively robust; the hind-limbs were long, slender, and had four toes. The skull was elongated, narrow, and triangular when viewed from the side. The front of the jaws were covered in a keratinous beak.
