Changzhousaurus
Changzhousaurus was a tiny, feathered dinosaur that lived about 120 million years ago in what is now China. It had big wings on its arms, smaller wings on its legs, and a fan of long tail feathers, kind of like a peacock. This little hunter is a close cousin of Velociraptor and Microraptor.12

Сонирхолтой баримтууд
Changzhousaurus is the only known early bird relative that had both large foot feathers and very long tail feathers at the same time.32
It had about 16 long tail feathers, which were about four times as long as its thigh bone, and they fanned out like a peacock's tail.32
Even though its arm bones were short, its wing feathers were the largest ever seen on a dinosaur that wasn't a bird, compared to its body size.3
The fossil is so well preserved that you can see clear imprints of feathers all around its skeleton.2
Changzhousaurus: хамгийн их асуудаг асуултууд
?How big was Changzhousaurus?
It was very small, about 34 centimeters (13 inches) long from snout to tail tip. That is about the size of a crow.1
?Did Changzhousaurus have feathers?

?What did Changzhousaurus eat?
It was a meat-eating theropod dinosaur. It had sharp, curved claws and teeth with serrations on some of them to help catch and eat small prey.1
?Could Changzhousaurus fly?
Scientists are not sure. It had large feathered wings, but its arm bones were short, so it may have glided or used its wings for other purposes like display.4
?When did Changzhousaurus live?
It lived about 120 million years ago during the Early Cretaceous period. Its fossils were found in the Jiufotang Formation in China.1
Домог няцаагч
Домог: Some people think Changzhousaurus could fly like a modern bird because of its big wings.
Үнэн: Scientists think it was a four-winged dinosaur that likely glided or parachuted from trees, not a true flier. Its exact flying ability is still being studied.3
