Definition of aetosaur
- … footprints (actually scrape marks) can also be identified as coming from two other large vertebrates: phytosaurs and aetosaurs, crocodile-like reptiles who lived around the shallow lake.

- Aetosaurs were low-slung animals 1 to 5 metres long with small heads and armoured bodies, built like the ankylosaurs of the dinosaur age or the extinct, car-sized armadillos that died out around 10,000 years ago.
