Heterodontosaurus is a small dinosaur that lived during the Late Jurassic period, around 200 million years ago. It was discovered in what is now South Africa. This dinosaur is notable for its unique teeth, which varied in shape. It had sharp teeth at the front for biting into plants and flat teeth at the back for grinding them. Heterodontosaurus was a bipedal dinosaur, meaning it walked on two legs. It was relatively small, measuring about 1.5 meters (5 feet) long. Its body structure suggests it was herbivorous, primarily feeding on vegetation, and it likely used its speed to escape predators.
