Notable Small Ornithischian Dinosaurs

Here are some notable early Small Ornithischian Dinosaurs:

Agilisaurus

Agilisaurus was a small, fast dinosaur that measured about 2 metres in length. It had long legs and a lightweight body, making it an excellent runner. Agilisaurus used its speed to escape from predators and to forage for plants.

Heterodontosaurus
