ความแตกต่างหลัก
- Ankylosaurus (10 m, ~6,000 kg) and Stegosaurus (9 m, ~5,000 kg) were similar in size but very different in armor design.

- 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.
