Heterodontosaurs were tiny herbivores, with short arms, and long feet, but still able to
combine bipedal and quadrupedal movement.
In Heterodontosaurini they featured large canines in their jaw, probably for scaring off
predators or other signalizing.

Abrictosaurus could be a toothless form of Heterodontosaurus, probably divorced
by some sort of sexual dimorphism, or matureness.
