1

Uragasaurus is known from just one well-preserved backbone bone from the front of the back, called an anterior dorsal vertebra.1

2

The backbone had a Y-shaped pattern of bony ridges that is unique to this dinosaur.1

3

CT scans showed that the inside of the backbone was filled with tiny air spaces, a feature called camellate structure, which made the skeleton lighter.1

4

Uragasaurus lived during the latest Jurassic period, about 149 to 137 million years ago.4

5

It belongs to a group called Mamenchisauridae, which were famous for their extremely long necks.1

6

This dinosaur was discovered in the Phu Kradung Formation, a rock layer that also contains fossils of sharks, turtles, and other dinosaurs.1

7

Uragasaurus is the first officially named mamenchisaurid dinosaur from Thailand.1
