About Abrictosaurus
What it was like
Abrictosaurus was a small heterodontosaur, a plant eater that walked on two legs. Some specimens have fangs at the front of the jaw and some do not, which may be a difference between males and females or between adults and young.
Its world
It lived in the Early Jurassic, in what is now Lesotho. It comes from the Elliot Formation, where it shared the land with its relative Heterodontosaurus, the long-necked Massospondylus and the hunters Dracovenator and Megapnosaurus.
How it was found
Hopson named Abrictosaurus in 1975. The name was a reply to an idea that heterodontosaurs slept through dry seasons.
