It was a small, fanged dinosaur species that wandered around the toes of other dinosaurs. Scientists say that the 2-foot-long Heterodontosaur lived about 200 million years ago.
The Heterodontosaur was covered in porcupine-like quills and had a blunt, bird-like beak, but this was no cute bird. Its fangs were massive, like that of a hog.
