Ouranosaurus Facts for Kids
Ouranosaurus was a large plant-eating ornithopod dinosaur from Early Cretaceous Niger. It was not a duck-billed hadrosaur, but it was an iguanodontian relative from the line near hadrosaurs. Ouranosaurus is famous for its tall back spines that likely formed a sail or hump, plus a beak and plant-grinding teeth.

4. It Was About 7 Metres Long
The Natural History Museum lists Ouranosaurus at about 7 metres long.
Kid Decode: That is a plant eater with small-bus energy.
5. It Had Tall Back Spines
Ouranosaurus had elongated neural spines along its back that may have supported a sail or hump.
Kid Decode: Its back looked ready to catch every kid’s attention.
6. The Sail’s Job Is Debated
Scientists have suggested display, body temperature, fat storage, or muscle support, but the exact role of the sail is uncertain.
Kid Decode: The sail is a fossil question mark wearing a very tall hat.
7. It Was an Iguanodontian
Ouranosaurus belonged near Iguanodon-like dinosaurs, not the later hollow-crested duck-bills.

Ouranosaurus used a beak to crop plants and cheek teeth to process vegetation.
Kid Decode: Clip in front, chew in back, repeat across the Cretaceous.
9. Baby Ouranosaurus Were Hatchlings
Ouranosaurus dinosaurs hatched from eggs, so babies can be called hatchlings.
Kid Decode: A hatchling Ouranosaurus had a future sail waiting in the blueprint.
10. It Shared Its World With Predators
Early Cretaceous Niger also preserved meat-eaters and giant crocodyliforms, so Ouranosaurus lived in a risky neighborhood.
