Utuntu dushimishije

Nipponosaurus was the first dinosaur ever named from Japanese territory, though Sakhalin Island was later annexed by the Soviet Union.1

The only known skeleton is about 60% complete and belonged to a juvenile, not a full-grown adult.1

Scientists used bone histology (looking at thin slices of bone under a microscope) to confirm that the Nipponosaurus fossil was a youngster.1

Nipponosaurus lived near the coast, and its body was buried in marine sediments, meaning it probably died close to the shore.1

For many years, some scientists thought Nipponosaurus might be the same as other Asian duck-billed dinosaurs, but newer studies show it is a valid, distinct species.1

The fossil was discovered in 1934 by miners digging a hospital foundation on Sakhalin Island.1

?When did Nipponosaurus live?

It lived during the Late Cretaceous, about 89 to 84 million years ago, or around 80 million years ago according to some estimates.2 1

?Where was Nipponosaurus found?

Its fossil was found on Sakhalin Island, which is now part of Russia, but was Japanese territory when it was discovered in 1934.1 2

?Was Nipponosaurus a dinosaur?

Yes, it was a type of duck-billed dinosaur called a hadrosaur, specifically a lambeosaurine.2

Gusenya ibinyoma

Ibivugwa: Nipponosaurus was a full-grown adult when it died.

Ukuri: The skeleton is from a juvenile, as shown by its small size and microscopic bone features.1
