Is an ornithopod the same as a theropod?

No. Ornithopods are herbivorous, bipedal or quadrupedal 'bird-hipped' dinosaurs. Theropods are primarily carnivorous 'lizard-hipped' dinosaurs, like T. rex.

What are some well-known examples of ornithopods?

Iguanodon, Parasaurolophus, Edmontosaurus, and Hypsilophodon are famous examples.

Can I use 'ornithopod' in everyday conversation?

It would be highly unusual. It is a specialized scientific term relevant mainly to discussions about dinosaurs.

What does the word 'ornithopod' literally mean?

It comes from Greek: 'ornith-' meaning 'bird' and '-pod' meaning 'foot', so 'bird-footed'. This refers to their three-toed, often bird-like feet.

Examples

By CEFR Level

Dinosaurs like Iguanodon were ornithopods.

The museum has a skeleton of a large, duck-billed ornithopod.

Paleontologists study the evolution of ornithopods to understand herbivore adaptations in the Cretaceous period.

The phylogenetic analysis placed the new fossil firmly within the clade of basal ornithopods, suggesting an earlier divergence than previously thought.
