酷東西

趣味知識

Wulong was only about 1 year old when it died, and it was still growing.1

It had two very long tail feathers that were more than 12 centimeters (about 5 inches) long, probably used for display.2

Wulong had feathers on its arms, legs, and tail, including fluffy down feathers and stiff flight feathers.1

Its skeleton was found lying in a natural pose, with all bones still connected.2

Wulong had more than 29 bones in its tail, which helped make it a good runner and jumper.2

Scientists studied the inside of Wulong's leg bones to figure out its age, the first time this was done for a microraptorine dinosaur.1

迷思破解王

迷思： Some people think all dinosaurs with feathers could fly like birds.

真相： Wulong had feathers but could not fly. It used its feathers for warmth, display, and maybe gliding short distances.1
