Wulong

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
