Fatgs divertents

1

Xiaosaurus means 'dawn lizard' because it lived during the Middle Jurassic, a time when dinosaurs were just starting to become common.1

2

Its thigh bone was only 11 centimeters (4.3 inches) long, showing it was a very small dinosaur.1

3

Scientists think Xiaosaurus might be a missing link between earlier plant-eaters like Lesothosaurus and later ones like Hypsilophodon.12

4

Only two partial skeletons of Xiaosaurus have been found, and they were damaged during digging.12

5

Xiaosaurus had a special feature: its upper arm bone (humerus) was straight when seen from the front, which is rare among early ornithischians.1

6

The fossils were discovered near Dashanpu in Sichuan, China, in 1979 and 1980.12

Anc discutà
Scientists are not sure exactly where Xiaosaurus belongs in the dinosaur family tree because its fossils are so incomplete. Some think it might be a nomen dubium (doubtful name).1
