Fun facts
Kulindapteryx lived about 168 to 166 million years ago, during the Middle Jurassic period.6
This dinosaur had special skin scales that split into bristles, which scientists think might be an early step toward feathers.1
Kulindapteryx is known from hundreds of bones found in two bone beds, including skulls and skeletons of young and adult animals.2
It was a small ornithischian dinosaur, about 1 to 1.5 metres (3.3 to 4.9 feet) long and weighed around 2 kilograms (4.4 pounds).2
The name Kulindapteryx means 'Kulinda wing', because it was found at the Kulinda site and had wing-like bristle scales.61
Some scientists think Kulindapteryx might be the same animal as another dinosaur called Kulindadromeus, but others disagree.2
