Yamatosaurus was a duck-billed dinosaur that lived in Japan near the end of the age of dinosaurs. It had a special jaw with only one tooth at a time in each spot, which is different from most other duck-billed dinosaurs. This plant-eater probably lived in coastal areas.21

Utuntu dushimishije

1

Yamatosaurus had only one tooth in each tooth socket at a time, which is very unusual for a duck-billed dinosaur.2

2

It lived about 72 to 66 million years ago during the Maastrichtian stage of the Late Cretaceous.3

3

The fossils were found in marine rocks, meaning the dinosaur's body was washed into the sea after it died.2

4

Yamatosaurus is one of the oldest known hadrosaurids, or duck-billed dinosaurs, from Japan.2

5

Its shoulder bone, the coracoid, lacks a bump called the biceps tubercle, which is a primitive feature.2

6

The name Yamatosaurus comes from Yamato, an ancient name for Japan.1
