- Ankylosaurus was covered in osteoderms (bone embedded in skin); Stegosaurus had large upright plates along its back.
- Stegosaurus lived in the Late Jurassic; Ankylosaurus lived in the Late Cretaceous — separated by ~80 million years.
- Both were quadrupedal herbivores relying on passive and active defense rather than flight from predators.
