吃：每樣都來一點奇特的羽毛恐龍白堊紀早期

Caudipteryx was a small, feathered dinosaur that looked a lot like a bird. It had a fan of feathers on its tail and wings on its arms, but it could not fly. It lived in China during the Early Cretaceous, about 124 million years ago.1 2

酷東西

趣味知識

Caudipteryx had long, symmetrical feathers on its hands and tail, measuring 15 to 20 centimetres (5.9 to 7.9 inches) long. These feathers were black with a banded pattern on the tail.1

Its discovery in 1998 helped prove that birds evolved from dinosaurs, because it had clear feathers but was not a bird.1

Caudipteryx had a short, boxy skull with a beak-like snout and only a few teeth in the front of its upper jaw.1

It was a fast runner with long legs and a stout body, about the size of a turkey.1 2

Scientists think Caudipteryx was secondarily flightless, meaning its ancestors could fly but it lost that ability.1

Fossils of Caudipteryx have been found with gizzard stones in the place where its stomach would have been, just like in some plant-eating dinosaurs and modern birds.1

關於 Caudipteryx 最常被問的問題

?How big was Caudipteryx?

About 72.5 to 89 centimetres (2 feet 4.5 inches to 2 feet 11 inches) long and weighed around 5 kilograms (11 pounds). It was about the size of a peacock.1 4

?What did Caudipteryx eat?

It was an omnivore. It probably ate insects and maybe plants, and it swallowed small stones called gastroliths to help digest its food.1 2

?Could Caudipteryx fly?

No, it could not fly. Its arms were too short to work as wings, and scientists think it was secondarily flightless, meaning its ancestors could fly but it lost that ability.1 4

?When did Caudipteryx live?

It lived during the Early Cretaceous period, about 124 to 122 million years ago.1 2

?Where was Caudipteryx found?

All Caudipteryx fossils have been found in the Yixian Formation in Liaoning, China.1 4

?Is Caudipteryx a bird?

Most scientists say it is a non-avian dinosaur, but a few think it might be a flightless bird. The debate helped prove that birds evolved from dinosaurs.1

迷思破解王

迷思： Caudipteryx was a bird because it had feathers.

真相： Caudipteryx was a non-avian dinosaur, not a bird. It belongs to a group called oviraptorosaurs, which are dinosaurs closely related to birds.1
