- Iguanodon (10 m, ~3,400 kg) lived in the Early Cretaceous of Europe; Edmontosaurus (12 m, ~4,000 kg) lived in the Late Cretaceous of North America — separated by ~65 million years.
- Both were large ornithopod herbivores that could walk on two or four legs.
- Iguanodon had a distinctive thumb spike used for defense or foraging; Edmontosaurus had a soft-tissue crest but no spike.
- Iguanodon was one of the first dinosaurs ever named (1825); Edmontosaurus was named nearly a century later (1917).
- Iguanodon's thumb spike was initially mistaken for a nose horn by early paleontologists.
