趣味知識

Daurosaurus is known from a partial skeleton that includes preserved soft parts, which is very rare for dinosaurs.1

It had skin scales that split into bristles, a feature that scientists think may be an early step toward feathers.2

The fossil site was once a lake, and the dinosaur lived in a landscape with lakes and changing plant life.2

Scientists think Daurosaurus may have lived in groups, because the fossil record suggests it was gregarious.1

The age of the rocks where Daurosaurus was found was first thought to be Late Jurassic, but later studies showed it is actually Middle Jurassic, about 168 to 165 million years old.2

Daurosaurus is one of several small plant-eating dinosaurs found at the same site, along with Kulindapteryx and Kulindadromeus.2

關於 Daurosaurus 最常被問的問題

?How big was Daurosaurus?

Daurosaurus was a small dinosaur. Its adult length is estimated at 1 metre, so it was quite small.4

?What did Daurosaurus eat?

Daurosaurus was a herbivore, meaning it ate plants. It had a beak for cropping plant material.4

?Did Daurosaurus have feathers?

Daurosaurus had skin scales that split into bristles, which scientists think may be an early step toward feathers. This is similar to the feather-like structures found on its relative Kulindadromeus.3 4

?When did Daurosaurus live?

Daurosaurus lived during the Late Bathonian stage of the Middle Jurassic, about 168 to 165 million years ago.4

?Where was Daurosaurus found?

Daurosaurus was found in the Ukureyskaya Formation in Zabaykal'ye, Russia. Its fossil was discovered at a site called Kulinda.4

?Did Daurosaurus live in groups?

Yes, the fossil record suggests Daurosaurus was gregarious, meaning it likely lived in groups.4

迷思破解王

迷思： Some people think all dinosaurs with bristles or filaments were birds or ancestors of birds.

真相： Daurosaurus was a plant-eating dinosaur, not a bird, but its bristle-like scales show that such features appeared in many dinosaur groups, not just bird relatives.2
